Live in a block of flats where there is two of us on the top floor. Separate flats next door to each other. My new neighbour is SO loud with her door. They are fire doors but I've been here 3 years and I'm always mindful of not letting the door just slam shut and instead holding the handle to let is close quietly because if you leave it to just shut then it slams closed and is very loud. She does this multiple times a day, tonight it's gone midnight, and then the way she locks her door is so loud, she seems to take forever to lock it and the whole thing is just getting on my nerves. She also has her TV so loud I can hear it through the wall (never heard the previous two neighbours) and she is doing DIY sometimes late at night. 10pm drilling the other night. I'd like to say something but don't want to come across as "that neighbour" WWYD?
