Beth’s mother, who is 78, has fallen and shattered her knee. Her mother is the primary caretaker for her father, 89, whose health has been worsening since major surgery a couple of years prior. As her mother faces weeks of recovery, Beth brings her father to another state to live with her while her mother recuperates. Beth takes him to a geriatrician, who diagnoses a vitamin B12 deficiency and begins treatment. Her father’s health and mood begin to improve and he seems much happier and healthier in her home than he did in his, where her mother controlled everything he did and frequently reminded him that he was getting old and infirm. In fact, Beth’s mother often complained about her father and the burden of caring for him, so Beth has begun to think that her father would be better off staying permanently with her, which would release her mother to live a happier life without these complaints. Her mother says that caring for her husband is her responsibility, not Beth’s. Beth’s father is fairly passive, admitting that he likes living with Beth, but not asserting this fact to her mother. The time has come to make a decision: Should Beth insist that her father is better off with her, or return him to her mother, who wants him back?
