Dear Mr/Ms (surname),

This is to request you to grant my son (name of son) ,a student in X B, leave for 3 days from Feb 28th 2013 to Apr 04th 2013. He is going to visit his grandfather, who is seriously ill. Whatever loss in studies he suffers,  we will try to make up for it.

Thank you.                                                                      Dated: 27th Feb 2013

Yours sincerely,
