    Mr. Brown was going away for a week. Before he left, (A)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. (B)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 one to come

and that (C)the piece of paper was of no use for him any longer, 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 (D)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."
