The old, battered guitar case lay open on the floor. He hadn't touched the instrument in months. The feel of the worn wood, the creation of music, used to transport him. His son, Alex, had taken up the hobby, his passion a stark contrast to his father’s apathy.

He heard the strum of a guitar coming from the living room. Alex was practicing, his voice a tentative echo of the music he was learning. He felt a lump rise in his throat, and the familiar sting behind his eyes.

He didn't move. He closed his eyes and listened to the music, remembering a time when joy was so accessible. Now, his hands felt leaden, the strings of his own guitar a burden.
