Tom is a good boy, but he cannot get up early. He often sleeps until nine or ten o'clock in the morning. His mother doesn't want him to be late for school. So she buys him an alarm clock. She says to him, "You must get up when you hear the clock ring" "Yes, Mum." Tom says. And from then on, Tom gets up when he hears the clock ring at six thirty every morning. One day his mother forgets to ring up the clock. And the next morning Tom doesn't get up at six thirty. It's time for breakfast. Mother goes to wake him up. Tom is in bed and his eyes are open. He says to his mother, "I wake up very early."
"Then why don't you get up?" Mother asks.
"But," answers Tom, "You tell me that I must get up when I hear the clock ring. So I am now waiting for the clock ring."
