Drinking is not bad unless you are irresponsible about it. If you are partying at someone's house and you can stay at that persons house all night, then that is responsible. I have friends that have parties at their house and as soon as you walk in the door you have to put your keys in a fishbowl, then they keep it in a safe place where noone can find it, so noone can get at their car keys until the next morning when everyone is sober. I'd say that is responsible.
