     My name is Jack. When my family moved to America from a small village in Guangdong, China, we

brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young

people should always respect the elders. Unluckily, this rule led to my very first embarrassment in the United

States.

     I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got

their food quickly because I always respect the elderly. As soon as I said that, her face showed great

displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about

how sensitive(敏感) Americans are and how they dislike the description"old". I then walked back to the table

and apologized to the wife. After the couple heard my 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 seventy or eighty, and

people who reach such an age have the most knowledge and experience. Young people 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 that a person is

going to retire or that the body is not working well. Here many people try to keep themselves away from

growing old by doing exercises or jogging, and women put on make-up, hoping to look younger. When I told

the couple in the restaurant that I respect the elderly, they got angry because this caused them to feel they had

failed to stay  young. I had told them something they didn't want to hear.

     After that, I changed the way I had been with older people. It is not that I don't respect them any more; I

still respect them, but now I don't show my feelings through words.
