To: Lucy From: Mary Dear Lucy, How are you? I have been in China for a week. People there are very friendly and a classmate invites me to her birthday party tomorrow. I'm glad to come but I'm also very worried and don't know what to do that day. I know you have been to such party before. Could you share your experience with me? Were you supposed to arrive on time? How did you greet them? Hope to hear from you soon! Love, Mary
