Elve Robinson appeals his conviction for unlawful imprisonment and second degree rape, arguing that the trial court should have granted his motion for a new trial because his attorney improperly prevented him from exercising his right to testify at trial. While we agree that his attorney acted improperly,1 we do not agree that his right to testify was violated under the particular circumstances of this case. We affirm, holding that where a defendant is articulate and assertive and aware of his right to testify, he waives that right by not asserting it before the jury’s verdict. We also hold that, to prevail on a posttrial motion, he must present some evidence of what his testimony would have been so the trial court can evaluate its potential impact on the outcome of the trial.
On August 8, 1995, Robinson was charged with one count of rape in the second degree and one count of unlawful imprisonment. The State alleged that on August 2, 1995, Robinson drove D.M. to the Northwoods Motel in Blaine where he raped her. At the end of the second day of trial, the court held Robinson’s trial counsel in contempt for his disrespectful comments to the court outside the presence of the jury and ordered him to pay a $500 fine. The court then recessed for the day.
The next morning, the defense presented its final witness and rested. The court excused the jury while it heard the parties’ exceptions to the proposed instructions. During these discussions, the court again held Robinson’s trial counsel in contempt because of his disrespectful attitude to the court, and then recessed. Neither of the contempt citations was related to defense counsel’s presentation of Robinson’s defense. Both involved remarks he made in response to the court’s rulings.
*533When the hearing resumed, the court explained for the record that Robinson’s attorney told the bailiff when he left the courtroom after the second contempt citation that he was not coming back. The court called defense counsel’s office to inform him that the jury was ready to proceed. Defense counsel responded that he did not think he could proceed and was going to contact his own attorney. The court then told him that there was a trial to complete and ordered him back to court. The court added that he could bring his own attorney if he chose, and he responded that he would do his best. Jill Bernstein, who appeared on behalf of defense counsel when the hearing resumed, advised the court that he “wishes this Court no disrespect and wishes to do nothing but to advocate on behalf of his client and prepare and present his closing arguments today.” She also stated for the record that she had asked defense counsel whether he needed a recess and he indicated he was ready to proceed. The proceedings resumed. At the conclusion of their deliberations, the jury found Robinson guilty on both counts.
A month later, Robinson appeared pro se before Judge Mura to ask that he be allowed to discharge his counsel, and an attorney from defense counsel’s office appeared and asked that he be allowed to withdraw. Robinson also moved for a new trial, contending that he had received ineffective assistance of counsel and that his attorney had interfered with his right to testify on his own behalf. The court noted that Robinson had not filed a motion for a new trial within 10 days after the jury returned its verdict as required by CrR 7.6(b), but extended the deadline by an additional 10 days, as permitted under the rule, to allow Robinson to file the motion. The court observed that defense counsel was capable and competent to file a motion for a new trial and that the contempt orders were based not on his presentation of the case but on his behavior outside the jury’s presence. In light of Robinson’s concerns, however, the court allowed defense counsel to withdraw and appointed the public defender as substitute counsel.
Substitute counsel for Robinson, Jon Ostlund, filed a *534timely motion for a new trial based on former counsel’s alleged interference with Robinson’s right to testify at trial. At the hearing on the motion, Ostlund admitted that former counsel and Robinson had discussed, as part of their trial strategy, the question whether Robinson should testify at trial and had agreed that he would not. Ostlund argued, however, that “things changed in this case when [former counsel] was twice found in contempt of court.” After the second contempt citation, Ostlund explained, Robinson lost confidence in his attorney. Robinson’s motion was supported by his own affidavit and by affidavits from former counsel and Bernstein, each of whom stated that Robinson had made his desire to testify known after the defense had rested. Former counsel’s affidavit added that, because he was so upset about his interactions with the court, he “only wanted to get this case done with and not be in court in front of the trial judge anymore than absolutely necessary in this case.” He therefore “refused to accede to [his] client’s request and did not ask the court for permission to reopen the case and allow the defendant to testify as he demanded.” At that point, Ostlund argued, Robinson’s failure to take the stand was no longer the result of a tactical decision.
The trial court denied the motion for a new trial. It noted that no one had said anything to the court or its staff about Robinson’s desire to change his earlier position and testify until after the jury returned its verdict. At a minimum, the court would have expected Robinson to say something when defense counsel proposed an instruction, after Robinson said he changed his mind, telling the jury it could not use his decision to remain silent against him. The court also noted that former counsel had delivered a good closing argument on Robinson’s behalf and observed:
Mr. Robinson has had no problems expressing his own opinion contrary to statements of attorneys in the courtroom after the verdict is rendered and I think he would have been just as capable before the verdict was rendered.
The defense then filed a motion for reconsideration to *535which it attached two memoranda from defense investigator Michael D. Sparks regarding conversations he had with court security officers. That motion was also denied. The court again noted that Robinson was both articulate and assertive, and explained:
[H] e sat all the way through argument, sat here after argument, he was here before argument and when I was going over with [former counsel] the matters he and I were addressing, there was never, ever an indication [that he wanted to testify].
DISCUSSION
A court may grant a new trial where it appears that one of the defendant’s substantial rights was materially affected. CrR 7.6(a)(8). A trial court’s ruling on a motion for a new trial will not be reversed on appeal absent an abuse of discretion.2
A defendant has a constitutional right to testify on his or her own behalf,3 but that right is in tension with his constitutional right to remain silent. To assure that courts do not appear to be encouraging a defendant to waive his right to remain silent, they may not ask him whether he wants to testify.4 Courts must also avoid intruding into the attorney-client relationship or disrupting trial strategy with a poorly timed interjection on the subject.5 We therefore rely on defense counsel to inform the defendant of his constitutional right to testify or remain silent and on the defendant’s conduct in not taking the stand as a valid waiver of his right to testify.6
Robinson not only failed to take the stand while the defense was presenting its case, but he also admits that he *536made a strategic decision to remain silent after consulting with his attorney. In other words, he admits he was well aware that he had a right to testify on his own behalf and concedes that the reason he did not testify was that he had chosen instead to exercise his right to remain silent. Thus, it is undisputed that Robinson waived his right to testify. In Thomas, the court observed that “the judge does not know the defendant is not testifying until the defense rests.”7 Once the defense rests, a court may therefore proceed on the assumption that the defendant has chosen to exercise his right to remain silent rather than his right to testify.8
The real question then is what was required to revoke that waiver after the defense had rested. We hold that if a defendant who has waived his right to testify does not bring his desire to change that decision to the court’s attention until after trial, he must submit, in addition to his own testimony and that of his attorney, a description of what his testimony would have been had he testified. This is necessary to give the court a basis to determine whether the testimony would have made a difference to the outcome of the trial. If it would not, there is no prejudice and no need for a new trial.9
Here, it is undisputed that the court received no indication from Robinson that he wanted to change his *537earlier decision to waive his right to testify.10 The court observed that while Robinson had spoken up on a number of other occasions, he sat silently through the proceedings following the second contempt citation and informed neither the court nor anyone associated with his chambers that he wanted to testify. The record reflects that Robinson is articulate and assertive, so much so that he interrupted both the court and his own attorneys several times when he disagreed with something they said. Robinson’s case, moreover, was tried not to the judge but to a jury, and the conduct that gave rise to the contempt citations occurred outside the presence of the jury. There was thus no reason for anyone to think that the presentation of the case—on which the trial court commended his former counsel—was in any way compromised by the contempt citations. There was a valid waiver of his right to testify which Robinson sought to rescind only after the defense had rested. The court was therefore entitled to rely on that waiver absent any affirmative indication that the defendant wished to revoke it.
The question remains whether Robinson received ineffective assistance of counsel when his attorney failed to inform the court that Robinson wanted to revoke his waiver and to testify A defendant receives ineffective assistance of counsel if the attorney conduct at issue (1) falls below a minimum objective standard of reasonable attorney conduct, and (2) there is a reasonable probability that the outcome would have been different but for the attorney’s *538conduct.11 If defense counsel’s conduct can be characterized as legitimate trial strategy or tactics, it cannot serve as a basis for a claim that the defendant did not receive effective assistance of counsel.12
Defense counsel’s failure to pass on Robinson’s request to the court fell below the standard. It cannot be characterized as legitimate trial strategy in light of his own admission that he did do so because he wanted to finish the trial as quickly as possible.13 But Robinson has not met his burden of showing that there is a reasonable probability that the outcome would have been different but for his attorney’s actions.14 Robinson failed to make an offer of proof or to otherwise explain what the substance of his testimony would have been or how it would have changed the outcome of the trial.15 There is no basis for concluding that the outcome would have been different but for counsel’s deficient performance.16

In re Detention of Haga, 87 Wn. App. 937, 943 P.2d 395 (1997), is distinguishable. In Haga, the defendant made an unequivocal demand to testify during presentation of the defense case. Here, in contrast, Robinson did not assert his right to testify until after the defense had rested. We note that the court in People v. Alcala, 4 Cal. 4th 742, 805-06, 842 P.2d 1192 (1992), cert. denied, 510 U.S. 877 (1993), a case cited in Haga, agreed with the position we are taking here. It held that, where the record fails to disclose a timely demand to testify, reversal may not be predicated on a claim that the defendant was deprived of his right to testify. See Haga, 87 Wn. App. at 940.

It is worth noting that although Robinson’s attorney apparently failed to consider them, there may also have been valid strategic reasons for not reopening the defense case, especially since the entire defense strategy—developed when neither counsel nor his client was upset—was premised on Robinson’s remaining silent.

Neither of the issues raised in Robinson’s pro se brief has merit. Robinson first argues that the fact that he apologized after the first assault made any evidence of that assault inadmissible. There is no legal doctrine or statute that gives an apology the significance Robinson would assign it. Uncharged criminal activity, moreover, is admissible under exceptions to ER 404(b) (evidence of other wrongs is admissible to show preparation or plan). Robinson’s contention that there is insufficient evidence to establish that the victim was placed in fear of physical injury is also without merit. The victim testified that Robinson struck her multiple times and punched her in the face when she attempted to leave the motel room, forced her to take off her clothes, threatened her verbally, and forced her to consume alcohol and to perform sex acts. She also testified that she thought he had a weapon and did not try to escape because she feared he was nearby at all times.
