I don't know how to say exactly what this song is about. It's about moving forward and giving up despair.
lyrics
i don’t believe in heaven. i do believe in [bad word]  it’s down the street from here, and we both lived there for years. we burned the calendars for warmth, and the alarm clocks just for fun. we closed the blinds to make [bad word] sure that we could never see the sun. you could set a watch by the bottle returns and the ashtrays overflowing on the floor. (what? 520!) nothing’s free but time when you’re so [bad word] poor. but the past was death row, and the future’s a battlefield. i hope we choose the right war. because i’ve been fist fighting gravity since the day i learned how to breathe, and i still wake up on the same cold floor i fell asleep on. so i won’t, but we shall [bad word] someday. i can’t do it alone, but i shall be free someday. i don’t know how to live, but i’m sick of learning how to die. vampirism is for poseurs in junior high. we made our own postal system to cross the continent. as long as freight [bad word] and loners pick up dreamers with thumbs, who needs governments to get a letter to you, or a mixtape to me, or a postcard to johnstown? what’s a thousand miles between friends? what’s a friend that’s not worth crossing a country? but i owe money and broken hearts from philly to sydney and back to vermont. (what? yeah!) i regret a million things and that’s only what i haven’t forgot. but the past was a mine field, and right now is a prison break. i hope we make it alive. when who we are doesn’t stop where the law begins, then we’ll storm their court houses to survive. so i won’t, but we shall [bad word] someday. i can’t do it alone, but we shall be free someday. i don’t know how to live, but i’m sick of learning how to die. vampirism is for poseurs in junior high.
