I've lived in my flat for 15 years and never once had a complaint about noise until my new neighbours moved in a year ago.
Since them, we've had a party twice. Both times they came over screaming sad swearing at us (never met them).
We play music through Alexa, so doubt it could be THAT loud.
Tonight us was my son's 18th birthday party. Six guests. Did some karaoke. Woman next door comes over literally screaming and shouting at me and was so aggressive and rude I feel shaken.
It was 11.45 on a Saturday night and the second time in a year I've played music and both times they did this.
A couple of months back they had a huge party with music and shouting and screaming outside in the front garden until 3am and I didn't complain I just let them enjoy their night.
Tonight I said to the woman "you have parties just louder with more people and I don't complain" and she said that was my perogative and I should have some respect.
She was do aggressive and rude, I'm really shaken
