I have a novel idea. Why doesn't the daughter let her live with her? Then she can smoke in the daughter's house to her hearts content.
Not that it has anything to do with the issue at hand, but the daughter is 68 years old, no spring chicken herself.
I would imagine it's pretty difficult for a woman her age to tend to a wheelchair-bound patient.
Your compassion is moving.
Because the daughter probably has a family and also works. This way, the old woman has care 24/7 in the nursing home. It's not always easy for a working family to take in the old folks.
