      We know the westerners like to plan for their time carefully in order to do all the things that are important

to them. So if your American or English friend asks you to dinner, he usually invites you a week ahead. But if

you really have no time and can't go to the dinner, you can ring him to say sorry. The dinner is usually served

at home, sometimes at a restaurant. You should get there on time, and don't forget to put on your fine clothes.

It is also a good idea to take some little presents to your friend, such as flowers, chocolates and so on. When

you are at dinner, you should also observe (遵守) some other customs. Here I'll give you some dos and don'ts

about them in the following:

1) Don't leave bones on the table or the floor. (You should put them on your plate with fingers.)

2) Don't use your bowl to drink soup, but use your spoon to help you instead.

3) Don't talk with much food in your mouth.

4) Don't ask others to have more wine. (This is quite different from that in China.)

5) After dinner, use your napkin (餐巾) to clean your mouth and hands.

6) Make sure small pieces of food are not left on your face.

      Then after dinner, you can stay there a little time. And your friend will be pleased if you leave in half an

hour or so. Next day, you had better ring him up to thank him for the good dinner.
