The old leather-bound journal lay open on the kitchen table. The scent of aged paper and faded ink filled the room, a perfume that always transported him. He’d been flipping through his grandfather’s entries, tracing the looping handwriting with his finger. The house felt quiet, the late afternoon sun casting long shadows across the room.

His phone buzzed. A friend had sent him a link. "Hey, saw this. Thought you'd be interested," the message read. It was a link to his biography. His eyes scanned the digital book cover. It featured a candid shot of him, taken years ago at a festival.

The introduction described his early attempts at songwriting, the struggles, the late-night gigs in dimly lit bars. He thought about the songs he wrote in his youth, and how they sounded. He chuckled, a sound of gentle remembrance, and he started to read.
