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 nearly sent away. After he came out of lock-up(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 a few policemen opened the door and came in.

“I saw there weren’t any policemen outside, Daddy” said the boy “So I went to the crossing and asked some to come.”
