A lot of things happen early in life these days, you'd be surprised. You've probably lived a pretty sheltered life, but kids can go through a lot of tough shit, especially from 15 to 19. Its a very scarey time, when life is constantly redefining itself, and the drug use doesn't help things much.
believe me when i say this, BUT I KNOW from experience. not being a dumb cunt though seems to aid survival through quite dramatically. people should learn to depend on no one but their own wits.
