I'm writing to expree my sincere thanks for helping me a lot when I stayed in America. It's really kind of you to allow me to spend such a period of great time with you and your families.

However, when I was back home, I found that I've fogotten to bring back my english dictionary book which was a gift from my American teaacher.It's really precious for me.Maybe it was left on the bookshelf in the bedroom. I'm wondering if you could help to sent it back to me ,and I will pay the post fee myself.

Thanks in advance and hope to hear from you soon.
