If they were to write about The story of my life They would have to mention you With every page they'd write There's another side to every story told If I were the ocean You would be the shore One without the other one Would be need something more We are the shadow and the light [Chorus:] Always love me Never leave me now Now you are the other side of me [Repeat] I have known the emptiness Of feeling out of touch and living life without you here Would be living half as much 'Cause I've a need that only you could fill If love was mathematical You'd understand the sum To the heart's equation Where one and one makes one and lonely equals me minus you [Repeat Chorus]
