well he bought a plane ticket super cheap to fly from my sister's to me. We decided he will stay with me for awhile but can rent a room on airbnb if we are not getting along well. He looked into the airbnb rentals and he is comfortable that there are lots of inexpensive and convenient places to stay. I told him I'd give him a week's notice if I wanted him to leave. Also my sister I think wanted a break. He's been there for over 5 weeks.
