Herbert Sunbury was given his first kite when he was a young boy. Every Sunday, he went to a nearby park with his mother and father. The three of them walked to a hill in the middle of the park and flew their kite. That was how the kite flying began. Herbert left school when he was fourteen. He got a good job in an office. He was a clerk like his father. He was not paid much, but it was a regular job. The family had a little party for Herbert's twenty-first birthday. Herbert was given a present - a big, new kite. After the party, Herbert went to bed and his mother and father sat talking. 'He's not a boy anymore,' said Mr Sunbury. 'He's a man now. He'll want to get married soon.'  'Get married!' said Mrs Sunbury in surprise. 'Why? He's happy here at home with us.' Mr Sunbury did not reply. He never argued with his wife. Two years passed and nothing changed. Herbert and Mr Sunbury went to work every morning. They came back together in the evening and sat at home. At weekends, they went to the park with Mrs Sunbury and flew their kite. One Saturday evening, there was a change. They had all been out in the park as usual and they were sitting at tea. "Can I bring a girl home tomorrow, Mother?' Herbert suddenly asked. 'A girl!' said Mrs Sunbury in surprise. 'Who is she? Where did you meet her?' Herbert had met the girl at the cinema. He sometimes went there on a Friday evening. Her name was Betty Bevan. Betty c ame for tea the next day, but her visit was not a success. Mrs Sunbury did not like Betty and Betty did not like Mrs Sunbury. 'Never bring that girl back to this house,' said Mrs Sunbury after the visit. 'You're a fool to go out with her.' 'I'm going to marry her,' said Herbert angrily. 'You're a fool,' cried his mother. 'You're a fool.'
