When I was 14, my dad came to me and said "I wouldn't mind getting completely pissed with you, so you've got an idea what it's like and why it's completely pointless". Although I can remember the first time I got pissed, I don't quite recall exactly when it was. But I do remember my dad picking me and my mates up. I was still OK, but the other two puked in the car. They came around the next day to clean it up, though.
Speaking of that, it looks like tonight is going to be a night with slow but steady alcohol consumption. Haven't been drunk in three weeks, and not seriously wasted in six (or more), though.
BTW, 16 is the legal age in Germany for beer.
