I think that as far as possible we have a right to a bit of peace in our own homes. I have lived in three different houses since I got married 40 years ago.
In the first (a small modern terrace) there was a young family next door, and the children played in the garden, which was right next to my sitting room. The house was small, and there was nowhere I could go to escape the shrieking. They weren't doing anything wrong - just playing on a slide (and paddling pool in the summer), but it felt relentless, and used to get to me at times.
In the second house (an inter-war semi), there was a couple who had got together after their respective divorces, and each brought a dog to the relationship. The people left for work at 7.30 every morning, and the dogs set up a howl and yapping counterpoint until they returned at 7.00pm. It drove me insane. There were children about (and I lived there when mine were babies), but none of them were as maddening as those dogs.
I now live in a Victorian terrace, and thought that the walls would be thicker and there would be less noise, but no. A family has recently moved in, and they are so noisy that it feels like they are in another room in my own house. The father is the worst of all - he seems to stand in the middle of the house and shout for the children, and when the football is on TV (he works in the sports industry) he chants and whoops as though he was on the terraces, which means that the children don't know any better. I hear the children now and then in the garden, but it's in the house that they are all so noisy. They have knocked down the wall between the reception rooms downstairs, so they use it all, and I can't move from one room to another to get away from the noise. They have also taken out the carpets and fitted wooden floors, which makes the noise so much worse - particularly when they run up and down the stairs.
It is selfish, I think. I know that everyone will make some noise from time to time, particularly children, but I didn't let my children behave like that. They weren't allowed to play outside before 9.00am, and came indoors in the evening, and if there had been screaming I would have brought them inside, where they were reasonably quiet.
They do need to learn that other people have to be considered, or that selfishness will spill over into other parts of their lives.
