Next weekend my parents go out of town and I might get the first chance in my lifetime to experience real life (getting drunk). I'm not going to pass it up.
And I seriously think it's pure luck that you haven't been banned. That, or the mod's like you enough to pass it off.
The following is of my opinion, and is in no way based on facts, and is [probably] not reflected on by other TF members:
Talldude, getting drunk is one of those secretive things you keep from your parents. Might sound like a troublemaker thing, but it's not that bad if you keep it at moderation and are responsible about it. The amount you drink is dependant on the next time you're going home. If you're only out for a few hours, drink enough to get a buzz, but stop there. If you're gone for the night, you can pretty much get wasted and not get caught the next day(if you can handle hangovers). If you have friends, get a little gettogether and experiment with it. Just know when to stop. I've had REALLY bad nights where I get to the point where you're so drunk, you don't know that you're still drinking, which makes it a whole lot worse.
