"What about the next morning when you've got a hangover, leaves in your pockets, and the Greek national anthem Sharpied on your forehead? Will your parents suspect anything?
I don't know any parent that would be okay with their child going somewhere to go drink. And for good reason.
I hope this guy doesn't come back and say he lost his left arm in a car accident on the way home."
Wow, that's awesome. Except for the hurting yourself thing. Under no circumstances drink and drive or get in the car with anyone who has been drinking. Dumb, dumb, dumb. Period.Here are my suggestions:
First, you could try saying you're going to go see a movie that starts late - like 10 or later. But you'll need a reason why u didnt go to an earlier showing - so you'll have to "do" something before hand (and sitting at a house won't work, else why did u put off seeing the movie till late?). So you'll have to do something, go to a sports game, out to eat with some girls ur parents don't know - something believable. Then go to see a movie starting late so that it's more logical for you to stay out than go home.
Also, I think it works best if you do several other window dressing things as well. First, let it be known to ur family throughout the week that ur interested in seeing a particular movie. Second, on that night, check in and do everything by the book. (This also means doing it before u get hammered). Actually if you're parents are skiddish, the girl thing might not be a good call, simply because they'd be worrying about that. Be inconspicuous.
But, mainly, you're screwed.
If you're parents have even a passing relationship with the other family, chances are it's going to get mentioned sooner or later - and that can be problematic (unless you're around this kid so much that either mom doesn't know one "so I hear bobby had fun at ur little stevie's house" reference from another).
Second, I don't know what things are like in Canada, but when I was in high school, parties got busted a lot. If that happens, and the parents arent home, the kid gets screwed over (sometimes even hauled in). Either way, his parents find out, and all this means whether u want to or not, it's unlikely you'll be able to spend the night over there anyway.
Oh - wait - I've just remembered this little trick. Do everything I told you in the first graf, BUT say you're doing it all with a different, third friend (and not the dude who's parents are away). If you can, don't even mention that other kid. That way, the partier's mom and ur mom might not mention it unless he gets busted.
But again this is a complex manuever not to be practiced by the amateur or faint of heart.
If there's any way to "bend" the truth, that's probably your best bet. But remember, sometimes sh*t hits the fan and its necessary to get the parents involved (like if some kid drinks too much and gets alcohol poisoning). In these situations, you simply MUST nut up and get the folks involved, no buts about it.
When I went to prom, my date through no fault of my own got alcohol poisoning. She had gotten to the house where we were all staying with her girlfriends before the rest of us got there and proceeded to slam way too many jello shots way too quickly. Fortunately, I was sober and responsible enough to make a tough but right decision to call her dad. I knew it looked really bad on my part, even though I honestly had nothing to do with the thing, but I also didn't have the know-how to deal with the thing on my own. And when her dad arrived, he was actually not upset with me at all - (the fact that, unlike most there, I was still able to speak a sentence probably had a lot to do with it.) So anyway, if things go haywire, call the folks.
And this conversation never happened.
(Note from my lawyers - And, if you are underage, do not drink and in writing these posts I think we're all presuming you're of age.)
