When two middle aged overweight white guys in suits on a 90 dg day knock on the door so they can offer to give you a free book entitled What the Bible Really Says...
Especially when you answer the door wearing your Virginia Theological Seminary tee shirt.
You smile sweetly and say in a friendly tone of voice, "No thank you. Have a nice day" while you close the door firmly.
Taciturn says we should have asked them in for martinis, which he was fixing in the kitchen when they knocked.
I have a feeling the book has a chapter about the evils of martinis in it.
