I was invited to mine not long ago. I didn't want to go, not that many would remember me other than being that weird chick with the blue mohawk. Though, I have kept up with some of my old friends from school...the other misfits that I hung out with and yeah, it's interesting to see those 'cool kids' didn't get too far but one of my friends that everyone said wouldn't go anywhere is now a real big shot reporter and whatnot.
Another reason I didn't want to go was, I married my high school sweetheart. Everyone thought we would be the couple that indeed stayed together forever. But, because of me, we split up. He couldn't handle being with a transmale..so, I really wasn't interested in seeing everyone looking at me, shaking their heads and saying things like 'she's the reason {Ex husband's name here} got a broken heart'
