There is no tradition for Halloween in Norway. Yes, as a pagan holiday, there used to be a celebration that got co-opted by Christianity, but the pumpkin-carving, costume-wearing, trick-or-treating version is new. I care not for the modern version of Halloween, in all its current mass-market plastic glory: In the US, it's become a carneval, where people where any kind of costume, not just scary or witchy ones. In Norway, they make the effort to be scary - and obnoxious. This is the fourth year of trick-or-treating in my neighborhood, and the second time one of my windows has gotten egged. At least I had plenty of soapy warm water on hand, since I happen to be doing the dishes.
