Dear Mr. Brown,
I'm now safely back home. Thank you very much for all the kindness I got from you during my stay.
Hope everything is fine with you there.
Now I wonder whether I could ask you a favor. When I came back, I suddenly realized that I had left my English dictionary behind at your place. It is a precious gift from my American teacher. Would you please be so kind as to send it back to me? I'll pay for the postage. The dictionary must be on the bookshelf in the bedroom. It is the one with a red cover.
Thanks and all the best.
以下根據字數可靈活豐富文章內容(Besides, the experience of studying in U.S.A is very unforgetable. You are so kind that you make me feel comfortable like I was at home. I wish I would go to U.S.A again and see you some day. Best regards.)
Yours,
