Americans think a great deal of about time. From childhood they learn to value time. As children, they were taught to be on time to go to school, to do work and to do everything. When they are having good time, they say that time flies. When a person is dying, they say he is livingon borrowing time.
Time is money, is knowledge, and is everything in America. A working American must work hard for 8 hours a day and 40 hours a week, that is the working time. On his spare time he also works for less money. Even Saturdays and Sundays are filled of activities. In the street you can hardly see a man who walk slowly. They walk very fast. In fact, they are running.
