i am your neighbour

a letter
　　dear sir:
　　i am your neighbour living just under your apartment in this building. recently it seems that you make a lot of noises late at night, probably working on something. i think i can understand why some people have to work hard even at night. we are all sometimes pressed by some urgent work that has to be finished within a limited period of time. however, i wonder if you can readjust your working schedule a bit to avoid making noises late at night.
　　the noise you make disturbs my study. as i am going to graduate from college this summer, i am busy preparing for my final exams. the noise you make at night has made it impossible for me to concentrate on my study. besides, many other neighbours complain of it. one neighbour complains that she is suffering from lack of sleep due to the noise and actually makes mistakes at work that didn’t happen in the past.
　　to be brief, if you could kindly change your schedule and make less noise, all your neighbours, including me of course, will feel very much obliged to you.
　　sincerely yours
