" A baby wasn’t an idea, as love was an idea. A baby was a fact. It was a being with a mind and a nature, and you could feel about it any way you liked, but a baby wouldn’t care. Just by existing, it demanded that you believe in a future: the future it would crawl in, walk in, live in. A baby was a piece of time; it was a promise you made that the world made back to you. A baby was the oldest deal there was, to go on living. "
― Justin Cronin , The Passage (The Passage, #1)
