Sample leave application to your principal for sister marriage
Most respectfully I beg to say that my sister's wedding comes off on the 10th February, 1998. As my father is alone, there is no one in the house to help. Moreover, I am the eldest son of my parents and I think it my moral duty to help them on this occasion. I have to make arrangements for food and lodging for the Barat.
So I request you to grant me a week's leave to enable me to fulfill my obligation.
