This song is about how old feelings can be brought to the surface very unexpectedly and we forget how intense they were. He sees someone that he loved as a younger man but as time has gone by and he sees her now, he not only appreciates beautiful things about her but becomes more introspective about himself.
Intimacy can be an uncomfortable and akward experience and when we're nervous we want to be close to people, but sometimes don't know how to. Insecurity is painful. Different people deal with loss in very different ways. This song is a very frank illustration of how much we are capable of love and how often don't see it come to fruition, but still work and struggle to make the best with what we have.
