"And a rock feels no pain, and an island never cries"

I'm the rock on the beach, the one you know.
I'm the shell in the sand, the one you like.
I'm the plants in the water that sail with the flow,
that cactus of yours - I'm the seventh spike.

I'm the stone in the road, the one you crossed.
I'm the bridge over the river you once gazed.
I'm the paint in those letters you once tossed,
I'm the moon in the sky that gets you amazed.

I'm the wood from the tree where you left your mark,
that purple flower on the green floor you stepped on - I'm it.
I'm that lonely bench that lies still in the dark,
the one you sat on once - now it just doesn't fit.

I'm the door and its lock that you just won't open
even if I give you the key that I've always been.
I'm the mouth that kept the words unspoken,
I'm the blood and the heart and all the dead things within.
