I have had Rats, at one point the house I thought I was living in turned out to be a warm heap of mostly stationary rats. I have also had water that came into the house after it had fallen on the roof. This is super important: if water comes in, is that even a roof? Isn't it just a very expensive, tremendously inconvenient colander at that point? There was a discoloration in the ceiling at the center of the living room, and when I touched it, my finger went straight through. It had the consistently of oatmeal. People don't make houses out of oatmeal generally, and in that moment, I understood why.
