【正确答案】Mr. Johnson,
I'm your neighbor in the building. I find there are always loud noises from your apartment these days, which affect the ordinary life of my family. I wonder if you can readjust your working time a bit and avoid making too loud noises at night.
My son Tom will graduate from high school this summer and he's thinking of going to some first-rate university after graduation. So he's work ing extremely hard to prepare himself for the entrance examinations. The noises you made at night have made it impossible for him to concentrate on his studies. Besides the problem of my son, my wife is also complaining that she's suffering from lack of sleep and she actually makes mistakes while doing her secretarial work in her office. As to myself, I'm a truck driver. And you know of course what lack of sleep may cause when a driver drives his truck on the highway and feels sleepy.
I feel sure that other neighbors in this building may have quite similar problems just as we do. So if you could try to change your working time, all of us would feel very much obliged to you.
