I lived in a dorm that was supposed to house graduate students. I was stuck with a sophomore exchange student and we shared a 1/1 apartment style dorm. She was messy, and very lazy. She would throw her food in the toilet, loud, never cleaned up after herself and would act really odd after a few beers. She would say how lazy American's are while she would sit in the kitchen area watching tv shows on her laptop and eating chips while crumbs fell to the floor (I'm not even exaggerating here). </br> I had to tell her she needs to do her part in cleaning because I can't keep cleaning the entire apartment every week by myself when 80% of the mess I was cleaning was hers. I had to teach her how to use a broom, and explain what each cleaning product does, how it's used and all that. Did she ever clean? Nope. So I started only cleaning my own stuff and my side of the apartment and of course had to maintain the bathroom because I had to use it too. One day we noticed roaches and I wasn't surprised as she always kept the apartment at 80F (we live in FL) so it would get unbearable in the apartment. Also the crumbs were everywhere and she never closed her snacks just left them open. </br> So she tells me, wait, she demanded I give her painters tape to tape the vents to keep roaches out. I was in the middle of writing a research paper and I did not care enough to go through and see if I had any painters tape. I told her I was busy and I need to finish this paper. She stomps back into the kitchen skypes her mom and starts yelling in Mandarin to her mom, clearly bitching about me. Then she slams her laptop and storms back into the bedroom area where I am working and says "you need to do your part and help we both live in this apartment!" Then she goes to delete me from her facebook friends list...lol.</br> At that moment I was at a loss for words because she had some nerve to tell me that I needed to do my part, so I just went back to writing my paper. No point arguing with her because clearly she is delusional. So after a week I moved out to live by myself because she got even crazier as the days went on and I took all my stuff that I bought for the apartment out of there. So she didn't have a microwave, a toaster, a shower curtain and bath caddy, bath mats, kitchen towels, and cleaning supplies (not like she ever used them anyway).
