We've lived here, link detached - our sitting room is attached to their garage for 15 years. Perfectly happily.
They moved in 2 years ago and the noise. Two very noisy children, aged about 10/12 who scream and shout at the top of their lungs. They do nothing to stop them. We have 3 teen DS ourselves, little noise, children on the back and other side, again, little noise. All families just normal family noise.
Then there is the dog, thrown out into the garden and left to bark for hours and hours, teased by the children, barking to be let in.
The front gardens and driveways are open plan so their children play ball games on our front garden. But this results in the balls hitting my car and damaging plants.
Finally after a year of this, (we tried to put up with this during lockdown, summer, accepting neighbours settling in etc) we explained that we understood children needed to play, but please could they do so a little quieter and also could they be a little more conscious about the dog barking. Also that other neighbours had commented to us about it to us. We didn't even mention playing at the front, only the noise.
Since then, they've blanked us completely and taken to slamming the doors in and out of their garage numerous times a day/evening which shakes our sitting room walls! Obviously we won't mention this now.
My AIBU is should we have confronted them in the first place and I'm also asking you to share your neighbourly tales of woe to make me feel better.
