　　The Chinese have a saying: Eat good things for breakfast; eat a big meal for lunch until you are full; but eat less at dinner. Many Americans agree that one should start the day with a good breakfast, but their ideas about lunch and dinner are different.

　　Lunchtime is over quick in the United States. Most Americans only give themselves time for a quick lunch before they go back to work or school. So they eat a small lunch. After work they think they will have more time to eat a big dinner. Also a quiet dinner at home with all the family talking about their day is a way to take a good rest after a long, hard day of work.

　　Eating at a restaurant(饭店) is also different. In China, people like to talk and laugh when they are eating. Very often you can hear people talking or singing loudly and they are just having a good time. In America, it is not like this. They want a quiet place where they can eat a good meal far away from the sounds of the outside world. If someone is talking too loudly, other people in the restaurant will look at him or her angrily. If some people are talking too loudly, the manager(经理) might come out and ask them to be quiet. The manager may even ask them to leave the restaurant.
