.......the brain can do weird stuff...
Guess we'll never know and there is much that makes no sense in this story.
It could be that the lady suffered a stroke of some sort. I have had a little experience with stroke affected people and they do odd things and they do not reason correctly. In one cases the person did not realize he had had a stroke. It was that everything "just got so confusing."
Maybe old folks need "minders."
