It boils down to caring. It bothers her to think she is caring less about certain things she used to care more about. Yes, she is certain, there are things she is moving away from, and other things she is moving towards, in terms of caring, although the exact perimeters of those things she is unclear of. It strikes her that there are many things in life which she once cared an awful lot about, but now hardly considers outside of times like this, when a feeling of regret makes her contemplate her lack of caring and a caring is reborn in her. At other times a random thought or news item can infuse her with a new caring. At such moments she sees the ease in it; the minutiae of her caring are like waves in an ocean conveying her. Still she worries about the particulars of her caring, and whether or not she is caring or not caring and in the optimal proportions.
