"But when we face the great questions about gravitation Does it require time? Is it polar to the 'outside of the universe' or to anything? Has it any reference to electricity? or does it stand on the very foundation of matter-mass or inertia? then we feel the need of tests, whether they be comets or nebulae or laboratory experiments or bold questions as to the truth of received opinions."

I hoped that Grace would be a little bit of the best of all of us: Scarlett's spirit, and my mother's strength, Marion's determination, and Michael's sly humor. I wasn't sure what I could give, not just yet. But I would know when I told her about the comet, years from now, I would know. And I would lean close to her ear, saying the words no one else could hear, explaining it all. The language of solace and comets, and the girls we all become, in the end.
