You come out of your shell when your drunk and say and do stuff that you normally wouldn't, although sometimes you make an ass of your self you can never remember and neither can annoy else, also you have a laugh and so does everyone else. Basically if you say "O I don't drink", straight away people assume your different, socially awkward and a bit boring, just get wrecked a few times in the first week and then you can make your excuses later on, like o I'm on anti-biotics and can't drink this week but I will come out Tbh its also shit going out sober unless your just down the pub or something, you really can't go out clubbing sober it just doesn't work
