"So what have you come up with? What is it like?"
"Think of it as a furnace with huge fire and smoke blazing out of it. Pinching smoke that rises far into space. Small and ugly monsters that live in the sewers keep coming to the furnace and keep mending the fire. They throw in everything they can find, just to keep the fire burning. You and I are also mending the fire, even though we may not be realizing it. And apparently, we are not even supposed to. We are not supposed to think that the smoke we breathe is poisoning our lungs, destroying our health, and that when it rains, all that smoke will be washed into the sewers where we live. We are not supposed to think about it, let alone protest against it, because everybody is mending that fire. It's normal and we are supposed to be normal, too."
