Halloween party?

Mom wants me to invite Yasu over so he can see all the trick or treaters (he's over from Japan for 6 months), so I thought I'd invite a few other people over too. I'm not planning any kind of big wacky party, just hanging out, handing candy to small children, eating some kind of food (pizza seems likely), possibly watching some movie or other such things. My dad will be home as well, so this won't be a loud party or else it won't be a late party. It probably won't be either. Anyway, if anyone wants an excuse to leave their house on Halloween but feels too old to go trick or treating and too boring to go to a real party, you can come over if you want. Costumes optional but encouraged, which is always true for visiting my house.
