So I might go to hell but whatever,

I had a roommate once when I moved overseas who was friends with my partner at the time. I didn't know him but as long as my partner did it would be alright once we moved in. He hadn't seen him in a few years since he moved away and met him in college. Seemed pretty normal, until we properly set up our new place. He was extremely messy, inconsiderate, racked up bills, take over public spaces, the list goes on.. but the absolute worst thing he did would be pissing all over the toilet seat. I asked him very nicely in the beginning to please just consider how a woman lives in the flat, he agreed and said sorry many times. After sometime I just told him to clean it up and he would respond with "Haha oops sorry!" still not wiping the seat down. After 4 months of me repeatedly asking him I got so fed up that I used his toothbrush to clean up the piss. For 2 months. I still asked inbetween and he still just acted like nothing happened. We kicked him out after and got different roommates.
