Young men/boys are let's say hard to deal with.

I'm truly sorry you had to go through that Jessica, if its any consolation we weren't all like that, personally I never did something contemptible like that due to peer pressure, unfortunately at least 4 out of 5 would .The single most ignorant age/gender group bar none. I have a long standing disdain of teenage boys, boys in their 20s aren't much better. When men hit their 30s they start to show signs of maturity, sometimes not even then. Everyone here has already said it, peer pressure, bravado, being an asshole, call it what you want.
