When I lived with my mom when I was young, my mother wouldn't let me pull pranks on Jehovah's Witnesses. We either didn't answer the door or she would go out and tell them "No thanks!"
It got to the point where they would skip our house.
Although there was a weird mid-aged woman that lived across the street from us. She never walked or drove. Just rode on skates.
One morning some JW's stopped by at her house. The woman answered the door and had let them in. They were in the house for a good two hours. My mother and I were wondering what the hell was going on in there.
The woman killed herself the following week.
