They Didn’t Know Who They Were Messing With
I used to have a terrible work schedule. I’d have to wake up at 2:30 am every morning so I could be at work by 4 am. My downstairs neighbors would blare loud music at all hours of the night and I could feel the bass through my mattress. I went downstairs and politely asked them to turn down the music, and they seemed to kindly agree.
As soon as I got back into bed, they turned it up even louder and kept it going until about 1:30 am. They didn’t know who they were messing with. Before I left for work at 3:30 am, I turned over my amplifier so that the speaker was facing the floor. I turned the volume up and set my guitar on top of it. I left for my 12-hour shift, and the feedback was still screaming when I came home. The neighbors never blasted their music again.
