Mr. Smith left his car outside his apartment one night, as usual, but when he came down the next morning to go to his office, he discovered that the car wasn't there. He called the police and told them what had happened, and they said they would try to find the car.
When Mr. Smith came home from his office that evening, the car was back again in its usual place in front of his house. He examined it carefully to see whether it had been damaged, and found two theater tickets on one of the seats and a letter, which said, "We are very sorry. We took your car because of an emergency."
Mr. and Mrs. Smith went to the theater with the two tickets the next night and enjoyed themselves very much.
When they got home, they found that thieves had taken almost everything they had in their apartment.
