I like the fight with a partner interpretation. I always thought, though, that it's a more general sort of fight (or this is how I've projected my life onto the song, at least). Everyone's life choices face the scrutiny of others at time and if you've taken a somewhat unconventional path you often wind up in places that put you out of step with the people around you. Sometimes this makes them question your choices because it means you seem to be "behind" in life or you're not as overtly successful as people think you should be.

This song is a defense of choices.
