Subject: Nuisance of stray dogs
Respected sir,
I beg to draw your kind attention to the problem of stray dogs in our locality. The number of these dogs is swelling every day. They are getting on the nerves of the residents of the colony.
At night, they start barking in chorus and create a hell of a noise, sleep becomes almost impossible. The sick keep tossing in their beds and the students cannot concentrate on their studies. Nobody dares to move out of his/ her house at night for fear of these dogs.
You are, therefore, requested to instruct the concerned staff to take away these stray dogs and rid us of this nuisance.
Thanking you
Yours faithfully,
Mahesh
