Mr. Henderson slammed the lid of the ancient piano closed, the discordant chords still echoing in the empty music room. His own playing felt flat, lifeless, mirroring the emptiness in his own life these days. His divorce was final, his apartment felt cavernous, and the joy he once found in teaching had diminished to a dull ache.

A courier interrupted his brooding. It was a framed photograph, a black and white image of a young man, a former student he barely remembered, standing proudly next to a grand piano. The inscription read, "Thank you, Mr. Henderson, for the song. - Ethan."

He traced the outline of the photograph, a ghost of a smile playing on his lips. Ethan, the troubled teenager who had found solace in music. He remembered Ethan’s shy smile, the way his fingers danced across the keys. A flicker of something that resembled contentment stirred within him.
