Only the Bottom Is Flat
One day, a client came into the mechanic’s shop. What was strange was that the car seemed to hobble as it slowly rolled in. The driver got out and pointed at a tire, saying that its bottom was completely flat. Logic would dictate that the entire tire was flat, but the client wasn’t having it.
“No, it’s just the bottom that’s flat,” the man insisted. He demonstrated to the mechanic that the rest of the tire appeared to be in good condition, and, much to the mechanic’s frustration, he was forced to explain to the client that the bottom of the tire being flat meant that the entire tire was flat.
