In the five different locations I have lived, I have had only one visit from any religious group, Jehovah's Witnesses, who arrived at the door of my flat just as I was stepping out of it to go to work.
"We won't keep you a minute …" said the lady.
"You got that right …" was my reply over my shoulder as I walked down the stairs.
I regard door-knocking as an example of the fundamental issue I have with Christians of any colour - the "I've got something, you need it, and it's my job to make sure you get it …" approach, which I find patronising in the extreme.
I would never be rude to someone who came to my door, but neither would I entertain them for longer than the time it takes to say goodbye politely, and shut the door.
