题目内容：
根据下列内容，回答题。When my family moved to America in 2010 from a small village in Guangdong, China, webrought not only our luggage, but also our village rules, customs and culture. One of the rules isthat young people should always respect eiders. Unluckily, this rule led to my very first embarrass-ment in the United States.
I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving foodto a middle-aged couple, the wife asked me how the food could be served so quickly. I told herthat I had made sure they got their food quickly because ! always respect the elderly. As soon as Isaid that, her face showed great displeasure. My manager, who happened to hear what I said, tookme aside and gave me a long lecture about how sensitive Americans are and how they dislike thedescription "old". I then walked back to the table and apologized to the wife. After the couple heardmy reason, they understood that the problem was caused by cultural differences, so they laughed
and were no longer angry.
In my village in China, people are proud of being old. Not so many people live to be seventyor eighty, and people who reach such an age have the most knowledge and experience. Youngpeople always respect older people because they know they can learn from their rich experience.
However, in the United States, people think "growing old" is a problem since "old" shows thata person is going to retire or that the body is not working well. Here many people try to keep them-selves away from growing old by doing exercises or jogging, and women put on makeup, hoping tolook young. When I told the couple in the restaurant that I respect the elderly, they got angry be-cause this caused them to feel they had failed to stay young. I had told them something they didn'twant to hear.
After that, I changed the way I had been with older people. It is not that I don't respect themany more; I still respect them, but now I don't show my feelings through words.
