A parting gift, how sweet:

“I lived in an up/down duplex. After I moved in, I learned that the downstairs neighbors had a hobby of purchasing new speaker systems and playing them as loudly as possible to see how loud and how long they could play before the speakers broke. No, I am not kidding. They openly admitted to this (I think they reviewed the speakers?) and even hosted parties to see which speaker system could get loudest. In the summer, my wife and I would have to spend 4 or 5 nights per week sleeping in the car. I tried to ask the neighbors to please turn it down at night, but that actually made things worse. They would just turn the music up and pretend they didn’t hear me. So, we asked the landlord for help. He didn’t care. The police also refused to help.

We supposedly had a shared basement but we could barely use it due to the amount of clutter they threw down there. There were times I could not get to my own washer and dryer because they had so much junk in the way. I later learned that they were too lazy to bring their clothes upstairs so they used the basement as a personal dressing room, which explained why they had clothes strewn everywhere.

Anyway, we eventually moved out because we purchased a home, but I didn’t tell my landlord that. I told him we were leaving due to a severe bug infestation. There actually were bugs in the basement… because I put them there. My neighbors pissed me off so much that I went to a feed store and purchased live worms for chicken feed in bulk. I put them in the (clean!) clothes they left in the basement; their socks, shoes, pockets, pants, EVERYTHING I could find. My landlord had to pay for an expensive exterminator and my gross neighbors had worms in their shoes, 10/10 would do again.”
