"If you're a curious child and you get a new dog, you discover all kinds of things. Gravity has new meaning, when you're racing down a slide toward your eager-beaver dog waiting at the bottom (uh-oh!). Friction has a new meaning, when your slippery dog escapes from the bath (soap+fingers=not enough friction). But love has a new meaning too, when you and your cosmic dog become the center of your own universe."--
