Roger was a thief，but he wasn't very clever. When he was in school, he stole apples or oranges from other children. Sometimes he stole pencils or books from other children. But he always got caught.

The teacher spoke to Roger's parents and they tried to stop him from stealing things, but Roger wouldn't stop. He kept stealing.

When he was older, he began to steal from stores, but he was still stupid. Once, he went into a store wearing the clothes he had stolen the day before. The still had the price tags（标签） on them, and the store manager called the police. They warned him that he would go to jail if he didn't stop stealing.

Then Roger decided to rob a bank. He planned everything. He got some gloves so that he would not leave fingerprints, and a mask so that no one would recognize him.

" But what if they recognize my voice?" he thought.

He decided to write his message on a piece of paper so that he wouldn't need to speak. He found an old envelope and wrote "give me all the money" on the back of it. He got a toy gun and went to the bank. He put on his mask and his gloves（ and showed the note to the bank clerk. The clerk gave him all the money, and Roger ran out of the bank and went home.

Ten minutes later he heard a knock on the door. It was the police. They had come to arrest him for robbing the bank.

" How did you find me so quickly?" asked Roger

" It was easy," said the police." Your address was on the envelope!"
