The old music box sat on a shelf, its delicate painted figures frozen mid-dance. "I don’t even know why we kept this," Daniel said, already picking up the bigger items. His sister, Rebecca, stood stock-still.

She remembered the sound of the music, the tinkling melody that had filled their childhood home. Their father had played it to her every night before bed. It was a sound now inextricably linked to the warmth of his presence, the feel of his hand on her head.

Carefully, she reached for the small, ornate box. As she turned the key, the familiar tune began, faint but clear. She closed her eyes, and let the music wash over her, a wave of bittersweet reminiscence, the ache of time passing and love lost.
