The wind picks up and papers flutter. That which holds no weight finds itself floating and shifting. Moving from simply a breeze, the winds increase and become a united force. A great gush from the skies funnels down and circulates itself. It begins its work of not just shifting and shaping but dismantling and destroying.
The funnel encircles the known structures and that-which-has-been becomes a pile on the ground. As the wind softens and fades, the brick wall has now returned to its former life as building blocks.
That-which-has-been now is that-which-will-be.
