I'm not really that noise sensitive, but I don't like loud noise and I really hate inconsiderate noise. I have a neighbour across the street whose princess of a daughter is learning the piano. This has been going on now for a few years. The piano is right at the front of the house, in front of a door and windows that are always open, and directly across the road from my bedroom window.
She was playing as early at 5.15am and as late as 9.30pm. I complained about it a few times and asked them to keep the door and windows closed before 7am and after 7pm, which they initially agreed to, but now it seems they can't be bothered. I will admit I haven't heard it before 7am for quite a while, but she regularly plays until 8.30pm or 9.30pm, and sometimes she'll play for hours over the weekend.
The girl is only 14, and like most teenagers has a very "me first" attitude, but the mother is at fault for not teaching her to have respect and consideration for other people who live around her. I've stopped complaining because I was only becoming "that grumpy old cow over the road". Now I just turn my TV up REALLY LOUD when she's playing and hope that it's at least annoying someone.
