1. The girlfriend/wife is out of town and you keep your MacBook Pro on her side of the bed while you sleep. 2. You don't let anyone touch your MacBook Pro unless they have relatively clean hands (doubly so if you're using a MacBook). 3. The only thing you'll ever put on top of your MacBook Pro when the lid's closed is an iDevice, and even then you're wary. 4. You think of the blinking white sleep-indicator light as your MacBook Pro's heartbeat. 5. You gave your MacBook Pro a name.
