Deal shuffled two decks of colorful cards together with quick, clever paws, then dealt out a hand — a mix, some from each deck, no two hands ever alike. She was a nimble raccoon-tween with a black bandit-mask of fur, in a chunky-cartoon plum vest lined with little card-pockets, a deck always riffling between her fingers. On the bench, two neat decks waited: one labeled from Mom, one labeled from Dad, each card a gene.
"Here's the thing everybody gets wrong," Deal said, riffling the cards. "People think you just get half of Mom and half of Dad, plain and simple. But it's better than that — it's a shuffle." She mixed the two decks and dealt a fresh hand. "Before a cell makes an egg or a sperm, it takes your two sets of genes — one from each parent — and shuffles them together, then deals out a brand-new mix. Some genes from Mom's side, some from Dad's, jumbled fresh." She dealt a second hand from the same two decks — completely different from the first. "That's why your brother or sister, from the exact same parents, gets a different hand than you. Same deck. Fresh shuffle, fresh deal, every single time. Nobody — except identical twins — ever gets dealt the same hand twice."
Deal hadn't always loved the shuffle. When she was small, she'd felt oddly bothered that she and her sister came from the same parents but were so different — as if one of them must be the "wrong" mix.
Then her uncle, a card-sharp of the old school, sat her down with two decks. "Feeling like you and your sister should've come out the same, little one?" he said. "Watch this." He shuffled the two decks and dealt her a hand, then dealt another. "Same two decks. Two totally different hands. Neither one's wrong — they're just different deals." He fanned out the cards. "That shuffle is the best thing about you. If everyone got the exact same hand, one bad card and we'd all be stuck with it. But because every hand is fresh, the whole family — the whole world — ends up full of different mixes. Different is the point." Deal had shuffled and dealt all afternoon, and the bothered feeling turned into something warm and proud. "I'm not a wrong copy of my sister," she liked to say. "We each got our own fresh hand. And a world of fresh hands is a strong, lucky world."
A soft knock came at the lab door. "Come in!" Deal called, cards riffling.
Pip slipped in, watching the cards fly. "Deal? My brother and I have the same mom and dad, but we're really different, and someone said that's weird. Is it weird?"
Deal barked a laugh. "Weird? It's the opposite of weird — it's how it's supposed to work." She patted the stool. "Come deal with me. My uncle taught me why you and your brother got different hands from the same deck, and once you see it, you'll be glad of it."
Deal set two decks in front of Pip — from Mom, from Dad. "Shuffle them together," she said, and Pip mixed them. "Now deal a hand." Pip dealt out a colorful mix. "That's you — some genes from Mom, some from Dad, shuffled fresh." Then Deal had Pip shuffle and deal again from the same two decks. A completely different hand came out. "And that's your brother," Deal said. "Same parents. Same deck. But the shuffle-and-deal happens fresh each time, so he got a different mix than you." Pip stared at the two different hands from the same decks. "Neither one is the 'right' hand," Deal said. "They're just different deals — and that's the good part. A family, a whole world, full of fresh, different hands is stronger than one where everybody got the same cards. Your particular mix, the one nobody else got dealt — that's yours alone. That's not weird. That's the whole beautiful trick."
Later, after Pip had gone off shuffling two little decks and grinning at every fresh hand, Deal riffled her cards and dealt one last mix, some from each deck, brand-new, one of a kind.
She thought about how wrong she'd once felt for being different from her sister, and about the two fresh hands she'd just helped Pip deal — same deck, different deals, both exactly right. There was a warm, proud gladness in it, a rightness like being glad to be no copy of anyone: the quiet joy of the fresh hand, of a shuffle that makes everyone their own one-of-a-kind mix, of a world made strong and lucky by being full of different deals. That proud, glad gladness of a-fresh-hand-every-time was, to Deal, the whole quiet joy of the shuffle.
