Disturb my sleep? No problem, let 'er rip!
Back in my uni days, I lived with two friends and one did a foreign exchange semester, so she sublet her room for half a year and this young policeman in training rented her room. Not only was he a bit of a pig (go figure), but he also loved to play his music pretty loudly at night.
Talking to him didn't help, the landlord would have said that a sublet is the original tenant's problem, and the original tenant was two countries away. I didn't want to move out over this because I knew I would be suffering for only a few more months. Yeah and I hope nobody asks why I didn't call the police for disturbance of peace on him.
So after another time of him blasting music after 23:00, me asking him to cut it out or wear headphones as I had class at 08:00, and him making a joke that uni students should be partying more and whining less (and then slamming the door with no change in music volume), I had enough. I lay in bed fuming, scrolled revenge stories on my laptop and brainstormed.
The next day, I went out and bought a seamripper. Did I destroy his whole wardrobe? Of course not, that's against the law! But he may have started wondering about the shit quality of his clothes. Especially if he did laundry and hung it out to dry after a nice, long night of listening to his music, it must have seemed weirdly prone to gradually splitting along the seams, often at the crotch and butt.
