On the estate where we live it's a big thing. Most houses are decorated and all the kids go out. We get people from all over the area coming to our estate as they know we do it in a big way, parents turn up with car loads of kids. Everyone gets sweets ready and the kids come back with loads of goodies. It's like a big street party with large groups of kids and adults all chatting and having fun. I love it, chatting with neighbours while the kids all enjoy themselves in safety. If someone can't take their kids out, there is always someone willing to let them join their "party"
We have a rule that we don't knock if the house has old people unless they have decorated the house. I must say though, there are very few houses that don't get involved. The old people enjoy seeing the kids and have as much fun as them. It's really a fun night.
