Jim was clever, but he never liked to work hard. He often said to his friends, "If I work hard, I will make a lot of money. But I want an easy job and a lot of money. That's the best."
So he could only be a thief (小偷). But he still thought it was too much work, so he only told his friends what to do and how to get money from others.
One day Jim sent one of his friends into a very large and beautiful house. He told him to steal some money from that rich (富有的) family.
It was evening, and when the man looked through one of the windows, he saw a young man and a girl in the room. They were playing duet(二重奏) on a piano. The thief left the house.
When he got back, Jim asked him what he got. But he said, "I didn't take anything. That family can't have much money. You know, two people were playing only the same piano there. They didn't have enough money to buy another one."
