Well, the religion part of things I'm already decided on. I'm terrible at it, and the option of drinking was something I gave myself, not something other people told me to try. So peer pressure isn't that relevant, actually.
But I'll keep the half-pint idea in mind, Razor, thanks for that. =P Hopefully I don't forget it in the mad rush with my friends getting themselves drunk and all. I'll be having a friend who'll be sober, at the very least, so he can watch over me. He's my best friend to, so I know I can trust him.
As for me crashing at someone else's house, unfortunately not. I'm not too worried about that part anymore though, I'll just leave the party early after I've had my fill. HOPEFULLY my parents will be asleep, so on the chance I do get drunk, they won't see it. Quite honestly, I'm more worried about the possibility of a hangover. I have no idea how those work, but if my friends and the movie is anything to go by, it doesn't look so pretty.
Also, how obvious is it when one's drunk? Tipsy? Buzzed?
Love you all for the help, by the way! <3
