Anecdotally, I can confirm this...

So I'm a little behind on this, but there was an interesting piece in the New York Times on bullying. Back when I was being bullied around in elementary school, it wasn't called "drama"- it was "goofing around," "just messing with you," etc. Same idea, different words. None of the kids who bullied me would have ever admitted to bullying--why would anyone admit to being mean? For them, it wasn't A Serious Issue That Must Be Addressed, it was just everyday joking around. I asked the lead Mean Girl a few years later if she remembered teasing me, and her response was, "I did? I don't remember. Sorry about that." She obviously meant it, so I suppressed my first urge to yell, "You what?!?! You don't remember making my life a living hell for an entire year??? You ruined my life!" Instead, I think I responded with something like, "Huh, whatever."
