The vinyl on the old record player spun, crackling slightly. Professor Silva’s office was filled with the sounds of a jazz record, something he always played on quiet afternoons. David looked around, the familiar surroundings now tinged with melancholy.

He saw the worn armchair, where he had spent hours discussing the nuances of music theory. He thought of the late nights, the lively debates, the mentorship.

A tightness gripped his chest. He felt an intense desire to relive those moments, to capture the joy and energy of their shared experiences, before they completely faded away. He looked at the record, the music a bittersweet reminder.
