As she plucked the strings in a slow, syncopated rhythm—down, down-up, up, down-up—something strange happened. The PDF seemed to glow faintly. A single line of text changed from black to blue:

She practiced every evening. The exercises grew harder—hammer-ons, triplets, a haunting fingerpicking piece called "The Dock at Dusk." The PDF never rushed her. It knew she was a beginner. A dummy, even. But it also seemed to know that she wasn't practicing to perform. She was practicing to remember.

She laughed. Grandpa Leo had been many things—a carpenter, a terrible cook, a lover of bad puns—but never a dummy. Still, three months after his passing, Marla missed him so much that even a silly PDF felt like a letter from beyond.

"Good. Now sing off-key. Grandpa's rule #3."
