Ive been invited to a halloween party on friday and im not sure what kind of drink to bring. The invite says to 'bring your own booze.' Im 18, but id say a quite a few people there will be underage. Should I buy cans of beer and share? Would that be a quick way of getting to know people? Im not a massive party person as you can probably tell lol. I have an unopened naggin of smirnoff someplace though. What would be appropriate?
