A man visited his lawyer and said to him, “My neighbor owes me $100 for food and wine and he won’t pay up. What should I do?” “Do you have any proof he owes you the money?” asked the lawyer. “No,” said the man. The lawyer said, “OK, then here’s what you should do. Send him a letter asking him for the $1,000 he owes you.” “But it’s only $100,” replied the man. “Exactly! That’s what he’ll reply and then you’ll have your proof!” said the lawyer.
