Dear Frank:
I am terribly sorry to tell you that I have lost the valuable book you were so kind to lend me last week. I read it everyday and intended to finish it next month. Last night when I came to my room, it was nowhere to be found. I will try to recover it as soon as possible. If I fail to find it, I will get a new book for you.
But I am afraid it can never take the place of the old one. Old books are like old friends. Once lost, they can never be replaced. They are connected with cherished associations which the new ones can never have. And for this irrecoverable loss, I am to blame. I was so careless with my things. This is a warning to me to be more careful in the future.
Yours truly,
Tom
Dear Kate:
Excuse me for my long delaying in returning to you your “Robinson Crusoe” which I read through with great interest. I had finished reading the book and was about to return it when my cousin came to see me. Never having seen the book, She was so interested in it that I had to retain it longer. However, I hope that in view of the additional delight thus afforded by your book, you will overlook my negligence in not returning it sooner.
Thanking you again for the loan.
Sincerely yours,
Tom
