I was surprised to see a man and a woman, nicely dressed, carrying some literature. "Oh, oh", I thought, "now I'm trapped, like a caged animal." They were very nice. They spoke briefly, offered me a pamphlet, which I accepted, and left.
I thought these folks would usually try to work their way into the house in order to try to sell you on their religion. Not this time. And now I think I know the secret to prevent this from happening. I had answered the door still wearing the white t-shirt I wore to bed. And it was cold out. And I hadn't realized how much the shirt has shrunk. That's one way to get my point across without even opening my mouth.
