Not sure but isn't the 'rules' where Halloween is traditionally celebrated that the houses that are decorated are the ones with the treats & those with no decorations are the ones that get tricked?
Don't have an issue either way, but I think those not participating should definitely be respected. Kids love dressing up, it's fun for them, so be it! BTW, not one of my kids has been interested in it at all.
With saying that, when it first became popular in my area, I wasn't expecting any kids, and had no welcoming decorations out, but 3 littlies came knocking on my door all dressed in scary costumes, anyway, the only thing I had was a bag of multi-chips for my own kids school lunches, so shared them out to these kids, only to have them all tell me in various ways "but we don't like chips"!
Must say I wasn't very impressed that year!!
No kids trick or treating last night my street, but my daughter is going to a friends Halloween party tonight, and is refusing to dress in a costume!
