Whenever 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 about 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."
