"Hey! Can you keep it down?" The words felt foreign on Michael's tongue. He hadn't confronted anyone in years. The house next door was shaking with some kind of music that he didn't even recognize. It was, however, loud.

He looked over at his collection of old records, their jackets bearing the marks of a life well-lived. He remembered the dances he used to go to, the energy, the freedom. He considered the music of the day, a constant reminder of the passing years. The thumping next door was a mirror to his own feelings.

He sighed, his fingers tracing the grooves of a favorite album. He was getting old. As the music next door continued, he knew he was not getting younger. He slowly smiled, remembering how good it used to be.
