I am almost 31 and never fitted in with cool crowds at school so I have never went to any of my class reunions. It would feel too fake because I know I really didnt connect with many of the people and the worst thing a person can do to someone is act like that use to like you when they treated you like complete crap and made fun of you in school. I ended up going to a school for "troubled kids" and I fit in because ya know they felt the same way I felt!! It wasnt about getting trouble with law, doing drugs, parties etc at the troubled school it was kids that had problems at home or their old school decided to be assholes to them. I think you should really think about the pros and cons on you going and see what comes up more important to you. Some people never change and fake their entire life trust me Facebook shows you that. When you get a friend request from someone that totally treated you so unhumanly they should still be ashamed of themselves then they have the balls to request you as a friend- NOT COOL. I actually closed my facebook account about a week or two ago due to the fakeness of all the people on there..its a sad world out there. I wish you the best of luck
