Tim: Wow, now you tell me! I had half my stuff moved in there already.
Dennis: The automated home is controlled by a touch screen which is hooked into a central computer.
Al: That's right. With the simple touch of your finger you can turn on your air conditioning, your stereo...
Tim: Or your lights.
Al: Red lights?
Tim: Oops, wrong district.
