Mr. Smith went to 3 it and saw a well-dressed middle-aged lady outside. The lady said that she lived in the house beside theirs, and that she had come to 4 them to their new home. The Smiths invited her in after apologizing for the state of the house. "Oh, 5 ," she answered. "Do you know in some parts of this 6 neighbours are not all 7 ? There are some streets where people do not 8 their neighbours, 9 their next-door ones. But in this street everybody is friends with 10 else. We are one big, happy family. I'm 11 that you will be 12 here." The well-dressed lady got a 13 when she came to visit the house the 14 time, because she found a quite 15 man and woman in it. Mr. and Mrs Smith had not had the courage to tell her that they were not the new owners of the house, who were to move in the next day, but the old ones, who have lived beside her for two years without ever having visited her or even noticing her existence (存在). | ||||
