Dear Emily, I like your TV programs 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 here are very different from those in my country, and I know little about them. 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 use the fork and knife? How can I let the family know that I’m thankful for their kindness? Love, Zhang Hong
