You can't choose your family or your neighbours unfortunately! We have a large block of flats opposite our house, it can be very annoying when people pull up out the front and toot their horns, especially when the baby is sleeping! Arrrgh!!
At our old house we had a neighbour who liked to play loud music, now I don't mind my music loud but when I can hear her music in my bedroom with all the doors and windows closed, that's LOUD. One day when I rang the cops to complain, the woman asked how loud, I said "can you hear it?", she said "yes", then I said, "I'm in my bedroom with all the doors and windows closed, does that explain how loud it is?" Not surprisingly the cops came pretty quickly, took them longer to get her to answer the door as she couldn't hear them over the music.
So, you have my sympathy.
