Madam,
Dated: September 10, 2006
I am a student of Class VI-B in your school. My sister reads in class VI-A. We have some common books to read. My father cannot affort another set of books. I appeal you to allow me to change my section. This change of section will help both of us to read from the single set of books. I shall be very grateful for this act of kindness.
Yours obediently,
