The two songs are like part one and part two for me personally. For a large part of my life I felt like a conctere girl hardened by life yet fragile inside. It was like if I were to cave in to it all I would fall down and break into a thousand different pieces. Much of that had to do with the fact that one of my parents was an alcoholic. Underwater makes me think of that person every time I listen to it. That person died in their alcoholism which left me to search for answers that were elusive at best and damning at worst. However thanks to the grace of God I am now able to say, I once was a Concrete Girl but now I am Golden! God bless Switchfoot! And LOBH of course
