I completely agree with you. I get sick of my neighbours and the noise of their children, strimmer, lawnmowers, BBQs, swearing, loutish behaviour.
I have young children who are in bed usually between 7 and 8. Generally, the noise gets louder and louder as the day goes on. The swearing is awful. Parties is a nightmare and I rarely entertain here because of it. I also have to bring the children indoors because of the language.
I've taken to wearing earplugs when I want to sit in my garden to read, really I feel I shouldn't have to.
No you are not being unreasonable.
Some people have no consideration. ?
