Mr. Smith had neither wife nor children. He liked nothing but drinking. He almost spent all of his money with drinks. Sometimes he went hungry, but he had to borrow some money to buy some food. One evening he met a friend of him in the street. The man invited him to have dinner in a restaurant. He was very happy that he drank too much. His friend stopped a taxi and ask the driver to take him home. Soon they reached in the door of his house. The driver drove away. But Mr. Smith couldn't insert the key into the keyhole. Just then a policeman went up, offering to help him but he refused, saying “The house is circled now. If you can keep it moving, I can open the door.”
