The weird thing was, my paternal grandparents were religious and didn't celebrate Halloween and were generally displeased that my brothers and I did.
However, my husband is Wiccan so Halloween is a huge deal for him. It's always been MY favorite holiday.
I had several neighbors on my block who were religious and did not celebrate Halloween. They would close their doors, shut the curtains and put a note on the door telling trick or treaters that they did not believe in it. They called it "Devil's night." LOL.
