Observing children and Interviewing older people

I am a volunteer in a elementary school. My primary task is talking and playing with American kids. The first time I talked wiht them, they felt very shy. However, if they regard you as their friend, they would become open-minded and sociable. They also like to tell you their secrets
If in the public areas, it depends on their personalities. If a kid is extrovert. He likes active. In contrast, if a kid is introverted, he may very shy in the public areas.
I interviewed some older American people. I realized that they are very emphasize the quality of life when they get older. They don't care how old they are. They would prefer to live naturally. They don't like to bother their children and like to live lonely.

American family

I interviewed some friends and talked about American family.
The first thing surprised me is alomost all American family have more than one child. However, America does not have any overpopulation problems.
I think the strutch about American family is pretty much same like China. However, there are still have some differences. The traditionalChinese family is husband working and wife doing housework. However, in America, both of them are working.
One may concerned the life about elder people. I think they have good quality life. Government provides health care, insurances whatever if they want. They still can live with their children. The reasons that they live alone are they don't like become burdens for their children and they feel free live alone.
The big problem is divorce. The divorce rate is almost 40% in America. It has serious negaive influences for children.
