Mr. Brown was going away for a week. Before he left, he said to his son, “If anyone comes to visit me, tell him that your father is away on business, and will be back in a week, then be sure to ask him to sit down for a cup of tea.”

“OK, Dad,” said his son. Mr. Brown was afraid his son wouldn’t remember this, so he wrote these words down on a piece of paper and gave it to him. His son put the paper into his small pocket. He took it out and looked at it every now and then.

Four days passed, but no one came to see his father. The boy thought that no one would come and that the piece of paper was of no more use to him, so he burnt it.

The next afternoon, someone knocked at the door. The boy opened it. A man was standing at the door and said, “Is your father at home?” The boy put his hand into his pocket at once for the piece of paper. He could not find it. He suddenly remembered he had burnt it, so he shouted, “No more.”

The man was very surprised. He asked, “No more? I met your father last week. When did it happen?”“Burnt yesterday evening.”
