I don't know. Last year I was invited to a 10-year reunion for secondary school (grades 8-10, as we change schools again for upper secondary, grades 11-13), and I was added to a facebook group where they were planning the event. I wrote a post there saying that I was certainly NOT coming to this reunion, that I'd rather have teeth pulled with no anesthesia after what they did to me, and was then bombarded by messages from previous classmates. Among those who messaged me were the two "leaders" of the whole operation, plus a couple of guys who were quite mean to me, and they claimed not to remember any of it. They were like, "I'm sorry, but I just can't remember doing any of that." I told them that I didn't buy it, because it's an attitude that basically puts all the blame back on me like I just imagined the whole thing. I set them straight, and neither of them replied back. Oh well.

I'm pretty hard to offend nowadays, because there really is very little anyone can say to me that I haven't already heard, and that I don't already think to myself on a daily basis. So for me it's more about eliminating my inner bully.

Don't let them get to you. Seems like you still have a pretty healthy attitude about it, so keep that up, and don't let them squander it. You ARE better than them, and therefore you don't need to do to them what they are doing to you. They are idiots, and I'm actually willing to bet that they are in denial of just how lousy they feel about themselves.
