Dear Mr. Brown,
How is everything going? I want to thank you for your help during my stay in America. Upon arriving china ,I found I had left my English dictionary in your house. My American teacher gave it to me , so it is very valuable. I think It might be somewhere on the book shelf in my bedroom. Could you please sent it to me by mail .I will pay the postage. Thank you very much. Best wishes for you !
Yours,
