The pool was too warm. That was the first thing — the water wasn't cold like the bathtub, wasn't the sharp gasp she'd been bracing for since the car ride. It was warm and it smelled like something she couldn't name, something between clean and wrong.
"Okay," said the instructor. Her name was Tracy. She had a whistle she hadn't used yet. "Arms out."
Margot was four. She knew she was four because people kept telling her, as though it were an accomplishment. Four and standing on the second step, water at her belly button, arms out like Tracy said.
The other children were in the pool already. Two of them were crying. One was laughing, held aloft by a father who stood waist-deep in the shallow end with the concentrated expression of someone carrying something irreplaceable across ice.
"Now lean forward," Tracy said. "I've got you."
She had two hands out, palms up, fingers spread, just below the surface. Margot looked at the hands. They were large and freckled and the nails were cut short. She had never had to evaluate someone's hands before. She didn't know she was doing it now.
She leaned.
The water came up her chest and she made a sound — not a scream, not a word, something her throat manufactured without consulting her. Tracy's hands were under her stomach, flat and firm, and Margot's face was six inches above the surface and her feet were off the step and there was nothing underneath her except Tracy and the water and whatever agreement those two had made.
"Kick," said Tracy.
Margot kicked. Her legs did something approximate, something she would later not remember. What she would remember — though she wouldn't know she remembered it, would carry it not as an event but as a physical fact her body understood before her mind filed it — was the moment Tracy's hands moved. Not away. Down. Half an inch, maybe less. The pressure under her stomach softened from solid to suggestion.
She didn't sink.
The water held her. Not like a hand holds — not gripping, not choosing to. It held her the way a floor holds, by being there, by having always been capable of it, by not requiring anything from her except that she be in it.
Tracy's hands came back. Margot didn't notice because they'd never quite left. She kicked to the wall and grabbed the gutter with both hands and Tracy said "good" and moved to the next child, the one who was crying the way you cry when you're afraid of something that hasn't happened yet.
Margot hung on the wall. Her heart was doing something fast and big. The too-warm water moved against her ribs. She looked down at the surface, which was distorting her body into shapes that didn't match what she could feel, and she thought something she didn't have words for — something that, if she'd been older, she might have called: the world is fuller than I was told. There is a thing underneath me that I didn't put there and can't see and it works.
She let go of the wall.
