Honestly, our way to deal with it is to simply not celebrate the day at all.
We have just explained to our children (4) that we do not celebrate that holiday, and on that day keep our porch light off, which here is the universal sign to not Trick or Treat at this home.
Our church does a big thing called Trunk or Treat, but even then, we chose not to celebrate at all.
The interesting thing here is, trick or treating is a dying tradition, but maybe it is just Maine. But here, trick or treaters is just something people used to do. Instead, places like churches,
grange halls, and town offices have big holiday festivities so parents can go to one place, instead of traveling to many strangers homes. This is so much safer. As an example, our rural church on Halloween will have 1200-1500 people come through the church on that evening.
