I don't think the complaining neighbour was an elderly woman.
I'm not sure that it matters.
Wherever we live, unless it is in a remote croft or something, we have to share space, and people should be considerate. There are shift workers, people with babies, insomniacs, those who are ill - lots of people want a bit of peace in their own homes. It's not unreasonable to want to be able to lie in if you want to, or to watch or listen to something on TV or radio without a lot of noise spoiling it.
Similarly, children need to play, and to run off excess energy, which is where the compromise comes in. My children weren't allowed outside until 9.00am (including in the garden) and weren't allowed to scream at any time. If they got too loud I warned them, and the third time I went out they were brought indoors, or I would take them to the park where they could run around and make as much noise as they liked. My current NDNs have four children, and they are all sent out into the garden (directly below my bedroom) in the morning, presumably when the parents are getting showered and ready for work. The noise can be really bad, and as an insomniac I find it often starts a couple of hours after I've finally nodded off.
I don't mind them playing in the garden after school, and manage to grit my teeth when they run up and down the uncarpeted stairs, shouting at one another; but it really annoys me when I am woken up at 7.00 by their shouting.
