Respected Ma'am,
This is to notify that I wish to visit a family friend in Dubai as it is their son's marriage this weekend. They are very close friends with my father and thus, my family has to be present at their wedding. Thus, this is a request to you for granting me leave for the above mentioned dates.
I would be highly obliged and I promise to complete my class-work and homework in time next week.
Thanking you in anticipation,
Yours sincerely,
Amrita Hazra
Class 6B.
