A friend described to me what it is like to be single and dating.
He said, "You are driving in your car through a small rural town in East Texas. Suddenly you have a blow out. You realize you do not have a spare tire. Fortunately you see a service station. You walk over and ask the operator for a fourteen-inch radial tire. But they don't sell new tires. The attendant offers to let you rummage around in a pile of used tires in the back. He says, 'If you find one, you can have it - free.' So you look at one used tire after another, searching for the one with the most tread and the least out-of-round."
