Lyric discussion by grey eyes 

I know the context in which the song was developed, but if you remove it from that context, this song could have greater meaning. It could be applied to any relationship that seemed impossible, and is on the brink of becoming a distinct and positive possibility... Only to be kept out of reach by some particular barrier.

For instance, an relationship of estrangement or unhealthy behavior between a parent and child that is suddenly getting back on track... But then either the parent or child becomes acutely ill or something, thus pre-emptively putting a satisfactory relationship out of reach.
