Dear Andy,

I am glad to learn from that you are coming to China and will stay at my home. My parents and I are

very pleasing to have you with me. Now let me tell you that we have arranged for you. I know the school

would organize a lot of things for you do in the morning. In the afternoon, I'll show you around and take

you to some place of interest. We'll mostly stay at home in the evening watch TV, playing games, and

meeting people. I'm sure we'll have a wonderful time or enjoy each other's company.

I'm looking forward very much to meet you soon.

Yours sincerely,

Zhao Mei
