Sometimes a Jehovahs Witness will knock on your door, and you can just tell them you aren’t interested thanks.
Obviously what they believe isn’t true, but that doesn’t make them assholes. If someone genuinely believes that them knocking on your door and talking to you could actually save your soul in the afterlife, I won’t ever count that as bothering me. It can be annoying sometimes, but that’s usually because I’m already in a bad mood and not the fault of the door knocker.
