Mr. Carrey worked at a big company. He went to work by bus. One day when he was standing at the bus-stop, he watched cars go by. Many of the cars were new Sherry 700s, and most of them were yellow.

Mr. Carrey was a person who did not like to be different from other men. He always wore the same clothes as other men, ate the same food as other people, and did the same things after work as they did.

Two months later, Mr. Carrey bought a new yellow Sherry 700. He was very pleased with it, and drove to work in it the next morning. When he saw all the other Sherry 700s, in front, behind and on both sides of him, he was even more pleased with his car.

Mr. Carrey parked his car in a big car-park near the office building, and walked to his office. But when he came back at five o’clock, there were so many yellow Sherry 700s in the car-park that Mr. Carrey did not know which car was his. He tried his key in some of the cars, but people passing by gave him a look which he did not like. So he stopped.

Mr. Carrey could do nothing but wait nearly forty minutes until his car was the only yellow Sherry 700 left in the car-park.
