Are there any mistakes? Dear Sir/Madam, I am writing to you to let you know that there is a problem with noise from your flat. Your children used to listen music and watch movies with a very high level of sound. I can hear almost every word. My kid can not sleep because of this noise. Moreover, I usually have a headache at the end of the day reasoned by your children’s loud actions. They jump and run - all this sounds like beats. This situation has been existing for a long time. As I remember, it started in September, when your children began to go to school. There is a silence in the morning, but after lunchtime they come back home and turn on TV or music. After an hour or two your children begin to run, jump, and play with each other in a very loud way. It happens every day except weekends, when, I guess, you are at home. I can find two ways to solve our problem. First of all, please, talk to your children and explain them how they should act. It would be better if they could watch movies and listen to music with a normal level of sound. Furthermore, I would be so grateful if your children could change the place for run and jump from home to playground. If you want, I could even look for them from my windows. If this unacceptable for you, then I can propose to put something soft on the floor, that will not allow noise come to my flat. Sincerely yours, Mary Rom.
