Some towns really don't seem to participate, glad to be somewhere it's catching on. Dorset in general seems more easygoing with it.
I was talking to another parent last night about what it was like 30 years ago in America, there were so fewer norms around it. Roving gangs of unmonitored sugar-frenzied kids in costume knocking on every door they could find for miles around, late into the night. Some of them would actually retaliate against houses not participating, eggs and toilet papering weren't a rare sight. It was a hell of a thing, but I'm glad the kids growing up now are polite and go home before 11pm. And there are norms around not knocking on houses unless they're decorated. The kids are very civil and tame these days, compared to what I grew up with. Not complaining!
