Lots of people taking the piss out of the OP, but I bet they wouldn't like these neighbours living next to them.
Frankly, they sound dreadful; We used to live next to a 45 y.o. couple who had 2 adult daughters and 2 adult sons, and they and their partners and the 9 kids they had between them, would come around every weekend from 9am til 6pm. (And some evenings from 4pm til 10pm.) And all summer they would be in the garden screaming and yelling, the whole street stunk of cannabis, and our garden ended up with a dozen beer cans over it each weekend! A couple of the kids behaviour was awful too. Spitting, screeching, and swearing.
In addition, even on school days, at least 4 kids were there, (under school age,) plus the foul mouthed mothers. Sometimes for 10 hours. Why they didn't stay in their own home just baffled me. They also had noisy barbecues every bleeding weekend too! Sometimes as many as 30 people came around and stayed til 2am.
6 months we stayed there, and then we moved on. It was private let when we were between homes. Unsurprisingly, this house and the one on the other side of them is up for rent at least once a year!
I am finding the attitude of some here quite condescending tbh. It's OK for people to take the piss, but I bet none of YOU would like to live next door to the OP's neighbours.
