Over and over. I was tempting fate. What would happen, I wondered, if the wall came down? Would the roof cave in? Would the weight of it falling cause the floorboards to collapse? Would roof tiles and beams and stone come crashing through ceilings onto the beds and boxes as if there were an earthquake? And then what? Would it stop there? How far would it go? I rocked and rocked, taunting the wall, daring it to fall, but it didn't. Even under duress, it is astonishing just how long a dead wall will stay standing
