Simply, Darnielle is a genius. He is the best living song-writer, in my opinion. This song is off the album, Get Lonely. It can be said to take on a plethora of meanings. One being plainly about a break-up and how he cannot mentally function afterward, being alone, lost, confused, and afraid. Another goes along with his childhood (a recurring theme, seen more evidently in the album, The Sunset Tree) , and waking up without his abusive, controlling, step-father being home. I like the first scenario better, personally.
And an astronaut could have seen the hunger in my eyes from space.
