When I was about 10, we had some Jehovahs come to our house, and started talking to my step-dad about being saved, and how we should be attending their church, and my step-dad looked at them and asked for their home address. They asked him why, and he said, cause I like to party, that's part of my lifestyle, and if you think you can come into my house and push your lifestyle on me, then tomorrow night, I'm getting a few friends together, we're coming over to your house, and we're going to push our lifestyle onto you.
We never had another one visit. I think they keep a list or something.
