@aral I have a downstairs neighbor who is a wannabe-singer and a smoker, and who often perches on her balcony listening to her own recorded voice from the phone's speakers and smoking well past midnight. She is well-off and can afford a place for band practices but has rejected every single piece of advice for reducing both the noise and secondhand smoke that regularly comes from her place. At this point I can either crowdfund a nuke and/or a new place to move away to. 🥴
