When you start talking about good and bad manners you immediately start meeting difficulties. Many people just cannot agree what they mean. We asked a lady, who replied that she thought you could tell a well-mannered person on the way they --71. occupied the space around them - for example, when such a person walks down a street he or she is constantly unaware of --72. others. Such people never bump into other people. However, a second person thought that this was more a question of civilized behavior as good manners. Instead, this --73. other person told us a story, it he said was quite well known, --74. about an American who had been invited to an Arab meal at --75. one of the countries of the Middle East. The American hasn't --76. been told very much about the kind of food he might expect. If he had known about American food, he might have behaved --77. better. Immediately before him was a very flat piece of bread that looked, to him, very much as a napkin (餐巾) Picking it --78. up, he put it into his collar, so that it falls across his shirt. --79. His Arab host, who , said of nothing, but --80. immediately copied the action of his guest. And that, said this second person, was a fine example of good manners.
