Many years ago I bought a new three piece suit. Thinking I might be able to do someone a favour, I put the old one outside with a sign on "Free to anyone who can take it away". Not long after a ring comes on my door, there stands a little man, "About your 3 piece suite," he said, "can you deliver it?" "No," I reply,"I don't have a vehicle." "Oh," says the little man "Unfortunately I can't afford to pay you for the suit, but I could pay for delivery."
