taxing

My roommate's mom lives in another state but uses our address to avoid paying her state's income tax. A couple of weeks ago, she came to visit family and conduct some business. She visited several family members and did her business, then she came to our house and was going to go home from here. Normally, she only stays three or four days, but while she was here, my roommate found out that there was a very slight chance she had been exposed to the virus at work, so the visit got extended to the 14 day quarantine period. She set herself up on the couch and stayed there watching movies on her iPad and not cleaning up after herself. I can deal with all that, but the woman has been here a week and has worn the same clothes the entire time. Our living room reeks. Now, we're under a statewide stay at home order for 30 days. As soon as she heard that, she announced that she would be staying the 30 days because this is the address on her Driver's license, and she doesn't want to get in trouble for being out. My roommate asked me why I haven't been using the common areas of the apartment, and I told her. So, now, her mom is pissed, but she's still not leaving. I don't know how I'm going to live for a month with a stranger who is pissy and smelly.
