QUOTE : Because it is the hardness of the floor, and the abrupt halt in momentum, and the unyielding nature of the surface, that causes a thing to crack. Even if it is not that thing's fault. And then we talk about this thing being broken, or it needing to be fixed, and not what part of the floor has played in the matter. Never the part about the floor being a constant threat. Even if it is a nice floor. Even if everybody wants one just like it.
