The old photo album lay open on the coffee table. She flipped through the faded photographs, a wistful smile playing on her lips. The pictures were a kaleidoscope of faces and places, each triggering a flood of recollections. He entered, holding a steaming mug. "¿Cómo estuvo tu día, cariño?" he asked. The effortless flow of the language, so familiar yet alien in his mouth, was a profound experience.

Her breath hitched. The voice was his, the words were hers. A strange sense of buoyancy seized her. He had picked up her mother tongue, the one she spoke every day as a kid.

She took the mug, the heat radiating through her fingers. "It was good," she replied, her voice soft. "Thank you." The scent of chamomile tea transported her, momentarily, to a tranquil garden.
