I'm surprised at how many people haven't had Mormons come to their house! We have had them visit every single house we've ever lived in. I try to be really nice to them. It seems like they always get sent out during the worst heat of the summer, so I always give them cold bottles of water. I don't do much to try and change their mind. I used to, when I was younger, but it is pretty useless, so I gave up. I talk to them for a few minutes and they leave. Then, I always wave at them when I see them around the neighborhood.
