Dear Mr. Brown,

How is everything going ? First of all ,thank you very much for offering me so much  help during my staying in America. But would you please do me a favor again? Because I forgot to bring an English dictionary back with me. Would you please send it to me ?Since It was given by one of my American teachers as a gift, I treasure it very much. It was probably left on the bookshelf in my bedroom. Besides, I will pay for the postage fee. Thank you a lot!

Yours sincerely,                                                                                                         Li Hua
