where would they rather have you drinking - a place that they don't know of or who you're with, hiding it from them where IF you were going to have a serious problem for say, alcohol poisoning, you wouldn't tell them and have a kid die because you were afraid to get in trouble.
OR
a place where they know where you are, who you're with, and if you were to have a serious problem, but chances are you don't, you can go to them for help
sorry for the total run-ons brother
