PS, I agree, though, that sometimes you can use the words of a song to make a pretty good guess about what the writer was thinking about...or maybe NOT thinking about. For example, Melani suggests the song is about "a much younger woman taking care of an older man." Two lines would seem to me to suggest that it's not a young woman, but a partner his own age: Long ago, I used to be a young man/And dear Margaret remembers that for me and Sometimes she sees her unborn children in his eyes. At least, that's the way I see it.

Aloha,
