You never did stupid things like that when you were a teen?
I definitely remember throwing snowballs at cars, throwing junk in a movie theater at other people, etc (although I'm pretty sure I was around 12 or 13). I don't blame my parents for my behavior because I was well behaved in school and at home, so they had no idea I was up to no good. :-D
I think part of the problem with today's kids is that parents are *too* strict, causing them to lash out. We live in a world of constant fear of predators, etc (some of this fear is warranted). My uncle was telling me that my grandfather allowed him to go out alone in the woods near their house and shoot cans and bottles with a .22 rifle. No way would a kid be allowed this much freedom today.
