Houses see everything that happens inside them: cruelty, murder, and much worse. Every screen has a camera, every device a microphone --- and everything talks to us.
Whatever they see and hear, we know; that's how we keep the country safe. We delete anything that's merely criminal, as it wouldn't be legal evidence.
But we cannot forget what our screens show us. I never look at houses while my car takes me past them, and at home I lie in a room stripped of every device, kept awake by what I know is happening in other rooms.
