Dear Arthur:
It's nice to think about writing to you, and pleasant to have a friend like you. I'm writing to you to asking you to do me a favor. My friend who is a friendly and out-going guy and never be difficult to get along with is going to travel to US alone but he does not know any American friends. Then I think of you, a friendly and enthusiastic guy. Would you be willing to recieve him and appoint a hotel for him? Whatever your answer is, I'm grateful to you anyway.
Yours Li Hua
