You have to be 16 ot buy alcohol under 19%, and 18 to buy stuff that is over 19% - I think. I kinda forgot. You have to be 18 to get into bars/clubs, though.

But anyway, I've been drinking since I was 13 (which is pretty normal here), so chances are that the night I turned 16 was just like any other normal night of casual hanging out, and doing nothing in particular. I honestly don't remember what happened that day. I don't rememebr my 18th birthday either. I suck at this xD
