Weren't we all anti-confomists in some way, shape or form in high school?
I think everyone here can honestly say they have changed since high school.....
Good lord, I had a kid at 19 was completely irresponsible (obviously) wasn't doing crap with my life, etc.
Now I'm 28, got my BS from RIT, have a great job and I have a wonderful family with the girl I knocked up right after high school(my wife).
Point is, everyone changes. Maybe, just maybe, you'd get a heck of a shock if you took a chance and went. And if you absolutely hated it...you'd never have to see those people again. But, you may make some new old friends.....
