I'm still trying to determine the meaning of the word "was".
What does "bad, playful behavior" mean, exactly? Is grabbing a women's butt playful? He may have thought so at the time. Some people think it's fun to this day. Is trying to take off a woman's swimsuit playful? Hey, sounds like fun, no?
The question is, what *didn't* he admit. He needs to point out which incidents in the story were false.
