Maybe she never got over the death of her father, and never found any other love, perhaps nothing more than that. In any case, it seems a poetic profile of some lonely (probably older) woman the author knew. I like it all the more because it could read on any number of possible histories for the woman.

It's often the songs whose meanings are the most unclear that are the most haunting and affect us the most deeply, I think. Don't you find that so?
