Can't Put My Finger On It

The sky is blue, but I don't remember why And same with you, must have met through some other life Some other time Some things i learned long ago And some things i already seemed to know But they fall out of my mind And all the pieces start to grow Oh and how far? I will never know But they grow out of my mind And some day, they won't ever hurt Dirt, rot, and sunshine back into the earth Where they remain in my mind
