"Assisted living" is what we refer to as Retirement Homes here. The resident basically looks after themselves, is free to come and go (after signing out) on excursions or shopping or whatever but all their meals are supplied in a common diningroom and for extra a month, their medications can be doilled out by the nurse on duty. There are workers that will also come up and help the resident shower twice a week if required.
I know with the mil.. she wasn't able to live in ^^^ that type of situation because she would have wondered off for sure and there is no personal there that would change her diaper. Violent residents would have been asked to leave.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
