an apology I am writing this letter to extend my sincere apology that the noise from my house has disturbed you at night. I have no idea that you would be able to hear it so much, so I feel terribly about that. As you may have guessed, I was trying to refit my living room in the evening. Unfortunately, this task is not as easy as I expect, and also has a negative impact on you. I have decided to call in professional builders to finish this work. They will work only during the day time hours so that you won not hear the noise at night any more. I promise. I do hope that you can accept my apology.
