I'm walking around it with a female friend and we enter a room where the ceiling is sagging badly. She points it out, I say I must get around to doing something about that. She begins prodding it with her finger, and the bulge in the ceiling moves about. It seems to be collecting a large amount of water there. Despite my protestations not too, she prods right through and the water comes pouring down.
I go upstairs to the room above with a male friend, to view the damage. The whole floor/ceiling is on the verge of collapse. despite my protestations not too, my friend recklessly jumps on the floor and falls straight through into the room below. I start walking around the edges of the fallen floor. Everything is now structurally unsound, the water has obviously been doing more damage than I thought. From the outside of the house there is a long crack down one side, and rumbling noises. Even the opposite end of the house, unrelated structurally, has a sense of the whole house being about to collapse.
