The advantage of noise

Wherever I drove my old car over 55 miles per hour, it vibrated terribly, so I decided to sell it. My first customer wanted to buy the car, and I battled with my conscience over whether or not to tell him of the vehicle's problem. Finally I did the right thing.

Expecting him to drop the deal, I was surprised by his reply. “That's okay.” he said. “I'm buying this car for my daughter. If she complains about a vibration, I'll know she's driving too fast.”
