AITA for telling a boomer couple to move out of their house?

NTA - people get very set in their ways at their age, and don't like change. They also seem to have a sense of self entitlement, not wanting to give anything in terms of leeway in so far as accepting that while their existence used to be far quieter and it's how they liked it, that they in fact (in spite of how much they like to think so) get to dictate to other people how to live in the street. Doesn't sound like you're doing anything out of the ordinary, they just aren't willing to accustom to change and are throwing a tantrum because they don't like that they have to hear kids making sounds while reading a book, where previously it was dead silent. You're going to have to try and find a way to deal with them (and the others) as it seems that they have zero problem with demanding you to do what they want, but ultimately you're going to have to live next to these people so unless you plan on existing in a standoff with them for some years to come, it's probably wise to assess the situation and see where you stand - if they are just going to be assholes about it, there isn't much you can do, just be aware that they are old people, they have way too much time on their hands and will be looking out for every little thing (trust me, I've seen this shit before, it's like they become private detectives with their chosen thing to obsess over when it comes to other people in the street, and they will all talk about you! it can be a pain the ass but really if its just kids being a little noisy, fuck em, they need to learn to get along with people and realize that they don't get to dictate who moves in where).
