Dear Mr Desai,

        I hope you are well. I have to make a request to you and your family, so I am writing this letter to you. 

        Perhaps you know that my annual examination starts next week. I am busy preparing for the examination. The trouble is that the music system is played at full volume at your place. It is natural that this disturbs me and my sister in our studies. Moreover, my grandfather is not well and he is also disturbed much. 

        May I request you, therefore, to play the music system at a low tone! This will help us a good deal. I think you will not feel ill and advise your family members also to play the same at a low tone. 

        I hope to get cooperation from you. 

Yours sincerely,
