They would probably see the concept of leaving the parents at nursing home as immoral since they see taking care of your elders as a kind of repayment for back when they're being nursed as a child.
Mildred and Montag hardly know each other, and are not in love with each other. Mildred's focus is on the "parlor family" and does not focus on Montag. When Montag asks her if she remembers where they met, she brushes it off, and cannot give him an answer. She doesn't feel as though it is an important part of their relationship. They sleep in separate twin beds in the same room, but do not really communicate with each other. They talk to each other, but there is no deep communication as there is when Montag meets Clarisse. It is also very evident that Mildred only cares for herself when she sounds the alarm on her own hvusband for having books in the house and reading poetry to her and her friends.
