My MIL is in assisted living. She was doing quite well going to the shopping center, buying groceries and relatively adjusting for a couple of months. However, while she was living with us, she frequently thought someone was going to pick her up and drive her somewhere (both the someone and the where was a physical impossibility because we didn't live within driving distance.) We didn't argue with her as she would just go out to the parking lot and eventually come back in saying that the people hadn't shown up. She is now doing that at the AL and they are probably going to put a wandering monitor on her and perhaps she won't be able to get outside anymore. Should I tell them this was common behaviour for her and relatively harmless? On one hand her grasp of what is reality isn't very accurate, or the other hand she seems to manage fairly well in her alternative reality.
