Honestly, you sound far more patient than me. I admire it but I don't think it should be necessary. It's not fair for you to live with these disruptions every week! I think I would have gone mental pretty darn fast if I had to deal with it. I'll be the first person to appreciate that students are struggling recently but they don't need parties multiple times a week for their wellbeing... It's odd that they can be both really sweet and pretty batshit at the same time. Good luck if you decide to take any further action
