Subject: Request to return a book.

Dear Niladry,
It is pretty long time you borrowed a book entitled “A Book of English Grammar and Composition” from me but you have not yet returned it to me. Perhaps you have forgotten it. However, Junior School Certificate Examination-2013 is knocking at the door. So, I have to study more and more. I have revised the syllabus of almost all the subjects except English Second Paper. At this moment I need it badly. Friend, I think you have already realized the importance of the book. So, I would be highly delighted provided that you return the book as early as possible.
Thanking you,
Mugdho.
