We didn't used to do Halloween in the UK when I was growing up but we did have Mischief Night on the 4th November. I reckon this was more fun. You didn't ask any householder if they wanted to be involved. You just went out and got up to mischief. More authentic I guess, but you could get into trouble, depending on what you did.
My wife is pretty good about Halloween. She does the pumpkin thing so the miniature ghouls know they can come and ring our doorbell. They invariably opt for the Treat.
Wouldn't it be nice if a couple could ask each other "Trick or Treat" ?
