The strains of a complex sonata filled the living room. Sarah leaned against the piano, her heart doing a frantic dance. Her son, Ben, was playing the piece with a skill that far surpassed her own, his fingers dancing across the keys with astonishing dexterity. Sarah, a lifelong pianist, had instilled in Ben a deep appreciation for music. Seeing him now, fully immersed in his art, filled her with a powerful feeling she couldn't quite articulate, a lightness that made her want to sing.

When Ben finished the piece, the room was silent for a moment before the applause began. Sarah clapped until her hands hurt, her face radiant with happiness.
