Christians in the form of Jehovah's Witnesses come to my door about twice a year. I'm polite, they are members of our small community. Two men came once when I was stacking firewood. I said I'd be happy to talk if they'd help me with the wood while we spoke. They left forthwith and speedily. More recently, a woman and her children came. She said "Can I speak to you about - oh look! What kind of ducks are those?" And we proceeded to have a lovely talk about wildlife in the area. Much better!
