Tom and John were brothers. They were in the same room and were in the same class. One day they were unhappy with each other. For seven days, they were not good friends. One evening, Tom was very tired when he was back from school. He put a piece of paper on the small table near John's bed. On it were the words: John---wake me up at 7:00 am.---Tom.
When Tom woke up the next morning, it was nearly 8:00 am. There was another piece of paper on the table. On it were the words: Tom---wake up. It's 7:00 am.---John.
