I didn't know what the noises until he screamed while climaxing slapping his girlfriend on her behind. It just sounded like he was shaking something really really fast and all of which ended in about 2 minutes. You right I should muted it, but I didn't what the sounds were after I just woke up that day. He even opened blind door below me, pulled out a rolling chair and started making squeaking noises with it. Before I put in my 30 day notice, I did or perhaps annoyed the people below unintentionally while I was on my laptop and it was on speakers.... And what? when I get mad I hearing this, I try to go find out if it's my roommates doing it, I can hear them suddenly stop?? Then I walk back into my room, sit back down, and it goes again. It sounded like there was another group of sounds in my roommates room, because one of them was walking around in there. It was all just so confusing at the time. This guy passes out at end and starts snoring under me. They don't know me but maybe I was annoying them without knowing during my short time I was there.
