    I just think at a birthday party you want your old friends and maybe new friends but you don't really want to be meeting new people. Especially at a suprise party. You don't want a bunch of people you've never seen before jumping out of the dark and yelling at you.
Yeah, well...whatever. I thought it'd be a good chance for NAFTA to meet everyone.
