Dear Ria

You know my final exam is knocking at the door. I have to revise all my subjects in a very short time. You borrowed one of my grammar books. That book is very necessary for me at the moment. I think, you have read the topics you needed. Please send me the book immediately. Hope, you will take it considerately.

With love,
Sumaya
