This makes me think of nature shows where trees and plants break and crumble rocks. If I come back in a thousand years will I find a pile of crumbled cement and bricks with ferns all over them. I am sure over the past several years I have seen these same ferns on this wall. This wall actually looks like the plants could be crumbling it.
