Mr. West wanted to buy his wife a Christmas present, but he was always very 21 , so he was never able to find time to go to the shops. At last, when it was the week 22 Christmas, and the shops were very crowded, he decided that he could not 23 any longer. He worked in an office, and usually 24 lunch in a restaurant, but one day he bought some sandwiches, ate 25 quickly and went out to a big shop near his 26 during his lunch hour.
The shop was full of women, who were also buying 27 during their lunch hour. Mr. West stood 28 at the edge of a crowd of 29 who were pushing forward to try to get to the people who were 30 necklaces and earrings. He tried to move forwards slowly, taking his turn with the others, but more and more women were 31 into the shop the whole time and pushing selfishly (自私地) 32 him. After half an hour, he was just as 33 from the people who were selling the necklaces as he had been when he came in, and his lunch hour was coming to 34 , so he decided to change his 35 of doing things: he put his head down, gave a sudden loud shout and started to 36 his way towards the 37 of the crowd as hard as he could.
The women around him became very 38 when they saw what he was doing, and began to scold (责备) him. “Why can’t you behave (做事) like a 39 ?”, they shouted.
“Ladies,” he answered them, “I have been behaving like a gentleman for the past half hour, and it has got me 40 , so now I am starting to behave like a lady!”
