I think its obvious we wont understand why he used the lyrics he did,but this album is personal to Charles the vocalist. Its most likely him writing about his memories of his teen years. We may not understand it,but i'd like him to explain each song for maybe a deeper meaning.
And to all you people who say Saosin does this better, I actually disagree. Secret and Whisper have a different sound and are on their own planet with it, I would say. They're faster and more melodic and ambient.
As for you lyric-haters, sometimes simple lyrics are just as effective as eloquent ones with flowery language. I admire Adam Young (Owl City) for his simplicity and limericky cleverness just as much as I admire Kevin Matisyn (Evans Blue, Parabelle) for his eloquence and emotional depth.
