The first chords of the guitar echoed in the living room, a sound that stirred something deep within him. He sat on the worn couch, his own guitar resting against the wall, gathering dust. His son, Leo, was engrossed in his practice, his fingers flying across the fretboard. He remembered a time when he was once the one who played music.

He watched the shadows play across Leo's face, a mirror of his own youthful passion. The hours spent mastering chords, the frustration, the triumph of learning a new song. He was happy.

He closed his eyes, remembering those times. He smiled. He had never expected this.
