I have a different point of view. This woman has been a caretaker for her mother and came for a visit. She wants to go out for a day of shopping and a movie.
As a former caretaker, I can see that this lady just wants to feel normal and do normal activities. I don't think she is asking too much. Sometimes we need to break from our normal routine.
She has only been there two days so I don't think she is overstaying her welcome. Remember, she has to go back to her care taking duties. I would be nice to take in a movie.
