When I turned eighteen, I had a Renaissance themed get-together at my house where everybody dressed up. We had an executioner, a barbarian, knights templar, a bard, ladies, wenches. All we were lacking was an actual keg and full pig's head.
Goddamnit.
Then my cousin took me out for cocktails and Mexican food a few days after. It was lovely.
Edit: Couldn't help but nottice a lot of people mentioning that they purchased lottery tickets. Here we can do that from age 16 but I'm not sure about everyone else.
