                                                                 Son's Help

      Mr. Lang worked in a factory. As a driver, he was busy but he was paid much. His wife was an able

woman and did all the housework. When he came back, she took good care of him and he never did anything

at home. So he had enough time when he had a holiday. A few friends of his liked gambling (赌博) and he

learned it soon. So he was interested in it and hardly forgot anything except gambling. He lost all his money

and later he began to sell the television, watches and so on. His wife told him not to do it but he didn't listen

to her. She had to tell the police. He and his friends were punished for it. And he was hardly sent away. After

he came out of lockup (拘留所), he hated her very much and the woman had to leave him.

      It was New Year's Day. Mr. Lang didn't go to work. He felt lonely and wanted to gamble again. He called

his friends and they came soon. But they were afraid the police would come. He told his five-year-old son to

go to find out if there were the policemen outside. They waited for a long time and didn't think the police

would come and began to gamble. Suddenly opened the door and in came a few policemen.

      "I saw there weren't any policemen outside, daddy," said the boy, "so I went to the crossing and asked

some to come."
