The bustling department store played music overhead. It usually just faded into the background. But as she browsed the scarves, a familiar melody stopped her in her tracks.

Her song. The song she had written during a difficult time. Now, it was being played in a store, a symbol of life and renewal. She felt an irrepressible urge to dance.

She watched as shoppers paused, some tapping their feet. The experience felt like being wrapped in a warm blanket. This was everything. She thought of calling her friends, but decided that in this moment, the moment of pure, shared joy, was best left untouched.
