For a few years I had to put up with hearing my sister get dicked by her boyfriend. Her room was RIGHT next to mine, we shared a wall. One day I got really sick of hearing it. For the most part they were pretty quiet but her boyfriend would make sounds that rivaled even the loud guy in "the world's loudest orgasm." It was so fucking annoying.

One day, shit was starting up again and I could once again hear it all through the wall. If anything the wall somehow made it worse because it's like it amplified all the lower frequencies of the shit I was hearing, causing them to permeate throughout my entire living space. No place was safe. Also I could feel my computer desk shake from all the commotion. Not fucking cool. Not cool at all.

That day, I decided enough was enough. I got up, marched out to the hallway and approached her door. I closed my eyes and barged right in, and just said "guys can you please be fucking quiet, this shit is ridiculous", turned around and walked out. I went back to my room and sat down at my desk. After a few moments of complete silence, the sounds of muffled laughter erupted from beyond the wall. My deed was done. From that day forward, I continued to pull that shit. It set a precedent and an expectation that shit needs to stay quiet.

If I were in this situation, I would be doing some weird shit. If they leave the door open, it's free game for me to do some crazy shit. I would probably just stand in the doorway and eat a sandwich or something.
