The Surface Tension of Us

The pool was empty at 6 AM, which was exactly why Elena swam then. It was the only time she could hear herself think, her body cutting through water while her marriage quietly dissolved on dry land.

She'd left her iPhone on the lounge chair—her small act of rebellion. No notifications. No checking if Marcos had texted, though she knew he wouldn't. He was probably still asleep, or maybe already at the padel courts, playing with someone named Sofia whose name had appeared too many times last month.

Elena surfaced, gasping. Fifty laps. Her fingers were pruning.

"You're in my lane," said a woman's voice from the pool deck.

Elena hadn't heard anyone approach. A younger woman stood there, maybe thirty, holding a towel. Beautiful, in that effortless way that made Elena's chest tighten.

"Sorry," Elena said. "I thought I was alone."

"You seemed like you were working something out," the woman said. "Relationship trouble?"

Elena laughed bitterly, treading water. "Is it that obvious?"

"You've been swimming angry for forty minutes. Also you left your phone face down. That's a conscious choice."

It was. Elena pulled herself from the water, wrapping herself in a robe that smelled of hotel chlorine. "My husband plays padel with someone he says is just a colleague. They spend three hours a day together. He comes back glowing."

"And you swim," the woman said. "I'm Carla, by the way."

"Elena. Do you always diagnose people's marital crises at dawn?"

"Only when they're swimming in my lane," Carla smiled. "For what it's worth? If he's choosing padel over swimming with you, that's your answer."

Later, over breakfast, Marcos slid into the booth across from Elena. He smelled of coconut sunscreen and someone else's perfume.

"Great game this morning," he said, stabbing at his spinach omelette. "Sofia has incredible backhand form."

Spinach. Elena watched it cling to his fork. Green and persistent, like the doubt that had been growing inside her for months.

"I went swimming," she said quietly. "Fifty laps."

"That's great, honey." He didn't look up from his phone.

Elena's iPhone buzzed on the table. An unfamiliar number.

"Aren't you going to get that?" Marcos asked absently.

"No," Elena said. "I don't need to."

She picked up her fork, speared a piece of spinach from her own plate, and finally understood exactly what she had to do next.
