My family moved to America last year from a small town in north China.
I had a part- time job waiter in a Chinese restaurant. One day, when I was serving food to a middle-aged couple, the wife said she was amazed at could bring their food so quickly. I told her I always respected elderly. Then I found the wife's face turned red. My manager heard my (word) He took me aside and told me that Americans were sensitive (敏感的) and hated the description of "old". I then walked back to the table and (polite) said sorry to the wife. After they learned about the reason, they understood that the problem (cause)by cultural differences, so they laughed.
In the USA, people think "growing old" is a problem. Here many people try to keep (them)way from growing old by exercising, like jogging or swimming. When I told the couple I respected the elderly, they got angry because this (make) them feel they failed to stay young. They didn't want (hear) that. "If I understood the culture of America better, I would not make them angry. "I said to myself.
Recently, I change) the way I treat the elderly I still respect them, but now in a different, less direct way.
