Dear Rose,

     I like your programmes very much. I'm now writing to ask you something about American social

customs .My American friends want me to join them in their dinner party. I am very happy and have

decided to go, but I'm a little worried about it, too. The social customs in my country are very different

from here, so I'm afraid of making mistakes. Should I bring a present, such as sweets or flowers? Should

I arrive on time or a little late?

At the dinner table, how can I know which fork or knife to use? How can I let the family know that I'm

thankful for their kindness?

Dear Wang Lin,

     It's a good idea to bring a small present when you go to a dinner party. Flowers are always nice, or

you may bring a bottle of wine if you know that your friends drink it. You should arrive on time or five to

ten minutes late. Don't get there early. If you're going to be more than fifteen minutes late, you should

call and tell them. Try to be free at the dinner table. If you don't know about choosing the right fork or

knife, just watch the other

people, and follow them. If you still have no idea of what to do, ask the person next to you. If you like

the food, say so. Of course, you'll thank them for the meal and for their kindness. It's also a good idea

to send a thank you card the day after. 

                                                                                                                                       Rose
