I think it's deeper then just Flowers liking some girl. I get the feeling that he thinks things aren't right with the world. In the beginning it says "Racey days, help me through the hopeless haze, but my oh my, tragic eyes I can't even recognise myself behind" I think that means that he may be feeling a bit depressed. "Out again, a siren screams at half past ten, and you won't let go. While I ignore, that we both felt like this, before it starts to show." He's thinking deeper thoughts than her, and is wondering if he should be with her if she's not concered around her. Like they used to be the same and feel the same way, he's seeing things differently now. "Why aren't you shaking? Step back in time, graciously taking, oh your too kind." He's saying "Why aren't you affected by this like I am? I took advantage of the simple times that used to be." The song is about how he's asking her if she sees the world in a different way then before, and if not, he would show her. Just my interpretation anyway :)
