You make a noise while eating noodles.

A: You must be really about leaving for America tomorrow, Li Ping!

B: Yeah. But I'm a bit nervous.

A: Nervous about what?

B: I don't know many of the and manners in the US. Could you give me a hand?

A: Sure.

B: What do they have in America?

A: Well, it's important to be on time when you're invited for dinner. It's to arrive late. Americans expect their guests to be on time.

B: Then how long may I stay there?

A: After the meal, don't leave at once. Or you seem to have come only for the meal. When your friends seem to be getting tired and running out of things, it's time to leave. The next day, call or write a thank-you note to say how much you the evening.

    This August, we'll welcome guests from all over the world. Some of them follow their own special cultural traditions. It's important for us to know about them.

    In many countries, such as Thailand, India and Malaysia, people believe that the left hand is unclean. So, it's not proper to use one's left hand to hold food, touch others or pass objects. Doing so may offend some guests.

    Some Westerners may be offended if you touch them or their personal things-even by accident. If this happens, say sorry politely.

    Some elderly Westerners may be offended if you try to help them without their agreement.

    People think numbers can be lucky or unlucky. Some Westerners avoid the number 13 because they believe it is unlucky.

    Muslims(穆斯林)do not eat pork, and words like pigs are not considered proper.

    People from Brazil, Italy and Pakistan do not give handkerchiefs(手帕)as gifts. They believe a handkerchief is closely connected with unhappy feelings.

    Wine is not sent as a gift in many parts of western and middle Asia, where most Muslims live.
