Wang Lin, a Chinese student in America, was invited to a dinner party. He was a little worried because he knew little about American social（社会的）customs. So he wrote a letter to Rose, a magazine editor（编辑）, to ask for help. Rose wrote back to Wang Lin and told him what to do. Here is the letter.
Dear Wang Lin,
It is a good idea to bring a small present when you go to a dinner party. Flowers are always nice, but you may bring a bottle of wine if you know that your friend drinks it.
You should arrive on time or five to ten minutes late. Do not get there early. If you are more than fifteen minutes late, you should tell them first. Try to be free at the dinner table. If you do not know how to use the fork and knife, just watch the other people and follow them. If you still have no idea what to do, just ask the person beside you.
If you like the food, of course, you should thank them for the meal and their kindness. It is also a good idea to send a thank-you card the next day.
Best wishes.
Rose
