I live in a ground floor flat. The woman in the flat above has two children, and she's expecting a third. She used to have a partner living with her, but he disappeared, although he turns up at times to take the children for the weekend. After he had moved out, she started having loud parties on Friday nights, which gradually increased to Saturdays and Wednesdays as well. Her music was so loud, I could hear it in the bedroom. Her stair leading up to her flat ran right behind my bed, and people would come in and out, noisily clumping up or down the stairs, and talking in loud voices. One weekend, an argument from one of her parties spilled out into the street, with women screaming at each other, and her parents, who live across the road, tried to get her inside their house, but the other woman followed them in and tried to assault her. This was around 7:30 am on a Saturday morning. Many of the neighbours complained to the local authority, and investigators came out to interview the neighbours. The noise has since abated, although in the warm weather, she ramps up the volume, opens her windows, and the entire street gets to listen to her questionable taste in music. I'm not a musical snob - I like most music, but can't relate to the stuff she plays most of the time.
