I would definitely do it if they paid me enough money, but I don't think that I'd even want to go to my high school reunion without the cash incentive. Even though I only graduated 5 years ago, I'd probably be one of the only ones without a kid, and the last thing that I want to do is listen to people go on about their little parasites. Small town mentality does not foster a lot of good will with me, and quite frankly, a lot of people would probably be hoping that /I/ didn't attend.
I know what you mean about people bullying those who were less popular, KinkyKatieJames, and though it happened to me, it was never a personal concern because I just don't really give a rat's behind about most of the people that I went to school with. There are a good number of people that I alienated defending other people, though, and every time I see them around town I get glares.
We only have one place to go dancing in town, so really, going there on a Friday night is practically like going to a high school reunion anyways.
