Lyric discussion by AlexanderDumbass 

I think the woman in this song is quite naïve in that she believes that the universe is full of all of these people working together happily in unison and function.

Nick believes the universe is full of so many people that we can't help but step on each other as we try to succeed.

She tells him not to be so arrogant as to concern himself with all of the world's suffering.

So why is he smiling at the end where she cries?
