Old Brown lived in a city. He had no job but he was rich because he was good at stealing(偷). He was never in prison. So none of his neighbors knew that he was a thief.

One day one of his friends went to see him, but he was out. His son, young Brown, came out to meet the man and asked him to have a cup of tea in the sitting room. About half an hour later, old Brown came back.

“Mr. White asked me to give back five hundred dollars to you, Mr. Brown,” said his friend. “Thank you, my friend,” said old Brown.

But to his surprise, the man couldn’t find his wallet. He looked very worried. “What’s wrong, my friend?” asked old Brown. “I can’t find my wallet,” said the man. “But it was in my pocket just now.” “Who was here?” “Only your son” “I see,” said Old Brown. “Don’t worry. I will get it back for you.” Old Brown went out.

Soon he came back with the wallet. His friend was happy and asked, “Did you blame(责备) your son?” “Please don’t speak loudly,” said old Brown. “My son doesn’t know I took out the wallet from his pocket.”
