Right. So, two days ago, there was a bar crawl, on which our 'friend' invited herself, and decided to get paralytic at 11:30. She refused to tell us, or the medical assistants, where she lived or who she lived with. So, reluctantly two of our housemates (first time meeting her) took her to ours, paying for the taxi themselves, at 12:30. From then, on our sofa, she proceeded to piss and throw up on herself and our housemate, she then laughed about it and still refused to tell us any details of where she lived or who we could call. Then, she pissed on me, knowingly. After this, we got someone she is friendly with to come and pick her up. Issue is, it's two days later and she is refusing to come and clean our lounge and our sofa. The whole house stinks of piss and won't stop smelling no matter how long we air the house for, or how much Febreeze we spray. We have had no apology either. So, my question. Should she come and clean it up?
