Poolside Mathematics

The pool lights flickered underwater, casting long, ghostly shadows across the lane lines. Sarah had been swimming laps for forty-five minutes—her therapist suggested it, something about endorphins and processing grief. But mostly she was just trying to exhaust herself enough to sleep through the night again.

She surfaced at the wall, gasping, as Marcus unfolded his tall frame onto the adjacent deck chair. Same time as last Tuesday. Same worn orange sweatshirt that had once been bright, before chemotherapy drained the color from everything they owned.

"Your sister called," Marcus said, not looking at her. "She's worried about you."

Sarah wrung out her hair, chlorine and lake water mingling in her eyes. "She doesn't get to be worried. She wasn't there."

"No one gets to be worried but you? That's how it works now?" His voice was tired, not angry. Just exhausted by the math they'd both been doing since the funeral—calculating who deserved what slice of suffering.

She reached for her water bottle and the bottle of vitamin D supplements the doctor insisted she take. "It's not a competition, Marcus."

"Isn't it?" He shifted, the old dogtags from his military service catching light against his chest. "You act like you're the only one who lost him. Like you're the only one who's been wandering around the house talking to empty rooms."

The truth sat between them like something dead in the water. Their son had died six months ago—a swimming accident at summer camp, the counselor's negligence so ordinary it was almost banal. They'd been bearing different versions of the same loss ever since, each convinced their grief was the correct kind.

"I heard you got a dog," she said suddenly.

Marcus's shoulders dropped. "A rescue. He's got anxiety issues. Figured we'd match."

"That's not funny."

"It wasn't meant to be." He stood up, the chair scraping against concrete. "Sarah, we can't keep doing this—pretending we're living separate lives in the same house. It's like we're both drowning and neither of us will reach out a hand."

She thought about the drowning mechanics she'd read about. How people fighting for air often pull each other down. How sometimes the hardest thing isn't sinking—it's trusting someone enough to let them pull you up.

"Bear with me," she whispered.

"What?"

"Your grandfather used to say that. Before everything." Sarah stood too, water dripping from her suit. "Come swimming with me tomorrow morning. Not to talk. Just... to move. Together."

Marcus studied her face, looking for something beneath the exhaustion. For the first time in months, she didn't turn away from his gaze. The pool lights flickered again, casting them both in the same uncertain light.

"Okay," he said finally. "But I'm not doing laps. I'm too old for that shit."

"We'll just float," she said, and for a moment, it felt like the beginning of something that might eventually be forgiveness.
