You don't have Halloween? It's my favorite holiday. We decorate everything with pumpkins and dress up and have a big feast. Muggles say it's supposed to be the time of year when the barriers between worlds are at their thinnest, so you can see spirits and magic they wouldn't usually.
I can't stand blood I'm afraid. But I suppose you don't have to do either thing if you didn't want to. We all know you're you.
