Alcohol

I've seen the effect of alcohol. I've never experienced it firsthand, but I've definitely been close to it. I'd say 90% of exchange students spend a lot of time on their exchanges drunk. They're given this freedom...or at least they can take that freedom when they're technically not supposed to...and they go crazy with it.
I've held hair back for people when they threw up. I've thrown way bags of puke. I've searched for someone running around drunk in the rain at 3 in the morning. I've been scared for someone's life when they were passed out. It's not fun stuff.
I've seen how foolish people act and I've heard the stupid things people say. I've seen the other side of so many personalities and I've seen will break down.
Alcohol's a serious thing and I really wish it would be treated as such.
