Letter to Friend for the loan of the camera
Behram Manzil,
Fatima Jinnah Avenue,
Faisalabad.
July 6, 2018
My Dear Asad,
Some of my class fellows have made a program to pay a visit to Murree during the summer vacations. I am also going with them. We have decided to go to Kohala, Kashmir Point, and some other places of interest. I would like to take as many photographs of natural scenery as possible. My camera is not in working order. I cannot get it repaired as I have already managed some money for the trip. Moreover, my camera does not take as good photos as does yours.
I request you to lend me your camera for a week. I assure you that I will take care of it. I will return it as soon as we come back from the trip.
Yours sincerely,
Akbar Raza
