I have accepted the history book you sent to me. Here I wish to express my thanks to you of your kindness. Now I am write an English article on friends and friendship. Eager to have a history book, I searched several bookstores for it. To my surprised, I couldn’t find the book I wanted it. I was worrying about it while you happened to appear. You immediately offered to lend me your. That was very kind of you. The book you posted to me will certain be helpful. Thanks again! I will return to you as soon as possible.
