"A man lived by the side of the road and sold hot dogs. He was hard of hearing, so he had no radio. He had trouble with his eyes, so he read no newspapers. But he sold good hot dogs. This man put up signs on the highway advertising his wonderful hot dogs. He stood on the side of the road and cried, "Buy a hot dog, Mister?" And people bought his hot dogs. He increased his meat and bun orders, and he bought a bigger stove to take care of his trade. He made enough money to put his son through college. Unfortunately, the son came home from college an educated pessimist. He said, "Father, haven't you been listening to the radio? Haven't you been reading the newspaper? There's a big recession on. The European situation is terrible, and the domestic situation is worse." Whereupon the father thought, "Well, my son's been to college. He reads the paper and he listens to the radio; he ought to know." So the father cut down his meat and bun orders, took down his signs, and no longer bothered to stand out on the highway to sell his hot dogs. Of course, his sales fell overnight. "You're right, son," the father said to the boy. "We certainly are in the middle of a big recession." Confidence"
