What does the world do?
In the US, we like to carve pumpkins into sinister spectres.
The insides contain many seeds which I like to coat with salt and roast in the oven.
The kids go from door to door in costumes, either scary or otherwise, and say "trick or treat". I have no idea why we say this, as all they want is candy. In my time, we went door to door and got serious booty. Today people don't trust their neighbors and do this pathetic mall thing.
Anyway, I love this time of year, too bad I am living in a town that never changes to beautiful fall colors.
