From the glory that is craigslist, a sixty year-old woman is looking to rent a room in her apartment. Usually that means a second bedroom. She's talking about her bathroom:
"My bathroom is large. You can easily put a twin air mattress in there. I only ask that when I need to use the bathroom, you or your air mattress are not in it.
I do ask that when you are in the apartment, you confine yourself to the bathroom. I do not feel comfortable with a stranger walking around my living room. This might change as I get to know you better."
Basically, it sounds like she's asking for a squatter. Except for $400 a month.
She sounds like she'd be a joy to live with.
