Skin

She was part of the trees, her skin was bark. She had water for her blood and sun in her eyes, she moved very, very slow. But she was alive and she was alone. She was moving towards the old walls that were built by men. Men that wanted to cut her down, to use her to build a bridge. But that was so long ago. She will have her revenge as she watches the bricks and morter crumble under her feet.
