When you start talking about good and bad manners, you immediately start meeting difficulties. Many people just cannot agree with  36  they mean. We asked a lady, who replied that she thought you could tell a well-mannered person  37  the way they occupied the space around them. However,  38  second person thought that this was  39  a question of civilized behavior than good manners. Instead, this other person told us a story about an American who  40  (invite) to an Arab meal in one of the   41   (country) of the Middle East. The American hadn’t been told much about the kind of food he might expect.   42  he had known about Arab food, he might have behaved better. Immediately before him was a very flat piece of bread that looked, to him, very much like a napkin.  43  (pick) it up, he put it into his collar(衣领) so that it fell across his shirt. His Arab host, who had been watching, said nothing,  44  immediately copied the  45 (act) of his guest. And that, said the second person, was a fine example of good manners.
