But the river was never the same water twice. One day it was a slate grey, heavy with autumn rain; the next, it was a shimmering ribbon of silver reflecting a stubborn April sun. Marek found himself frustrated. He wanted the original peace, not a new version of it.

"It’s always different," Marek complained. "That’s the problem. I’m trying to get back to how it was."

"It’s different today," she said, nodding toward the water.

Marek lived his life as if he were waiting for a replay. He would sit by the same bend of the Vistula River every Tuesday, hoping to feel the exact same rush of peace he had felt one summer afternoon years ago. He wore the same wool coat, brought the same thermos of bitter coffee, and tried to think the same thoughts.
