Mr. Brown was going away for a week.
Before he left, he said to his son, "if anyone asks for me, you can tell
him that your father has been out for doing something, 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. But he was afraid his son couldn't remember this, he wrote these words
down on a piece of paper and gave it to him. His son put it into his small
pocket, 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 there was no man to come and that
the piece of paper was of no more use for him, so he burnt it that evening.
The next afternoon, someone
knocked at the door. The boy opened it. A man was standing at the door and
said, "Where is your father?" The boy put his hand into his pocket at
once and looked 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."
