Given enough time nature will take back her own. This photograph is of a side wall of the building next door. Because it is somewhat secluded, maintenance people don’t get to see it very often and the result is the vegetation growth and masonry decay are taking their toll, creating a kind of wabi-sabi wall.
Many years or centuries from now, if it’s left alone, what looks like a wall today will be nothing more than a mound of thick vegetation with a tree or two shading the birds and animals that live near by.
It’s a comforting or disquieting thought, depending on one’s point of view.
