One of my friends recently moved to America from Greece and we were attempting to explain Halloween to her.

Grecian: I don't really get Halloween.

Friend: You go to strange people's houses.

Friend 2: In costume!

Friend 1: Yeah, and usually in the dark...

Me: You basically do one day a year what you're never supposed to do. You go up to strangers and take their candy.

Grecian: You have no idea how weird this sounds to a non-American.
