A house 2 streets away was having a party (wedding). My uncle lives next door to them and he was invited. They had a bouncy castle outside their back gate on public land (used to be a play area but the equipment got pulled down a few years ago). There were hundreds of people.
Extremely loud music to the point of being able to hear every word in our house, we had to shut all windows.
This went on from 2pm until 5:30am!!! There are three huge blocks of flats right behind there house each 12 floors high, 4 flats each floor so that's 144 flats, plus at least 75 other houses surrounding them.
The following morning, DP went to work and discovered his car, which is parked on his uncles drive (so right next door to the party), was covered all one side in some sort of purple sticky substance (presumably a drink) which must have been done deliberately. It was covered.
So not only did they keep the whole neighbourhood awake, they deliberately caused damage to a car.
AIBU to think a party going on until 5:30am is wrong??
