Peter is eight years old. He doesn't like getting up early in the morning. He is often late for school. Peter's mother is not happy about this. One day, his mother gave him a clock and asked him to get up at 7 o'clock in the morning. After that, Peter can get up earlier. But one morning, the clock didn't work and Peter didn't get up at 7:00. His mother entered his bedroom to see him. Peter was in bed and his eyes were open.
"Why don't you get up? "His mother was unhappy.
"Because I didn't hear the clock, so I'm waiting for it". Peter answered.
