The sun's rays slanted across the dusty surface of the old trunk. Sofia felt an impulse to hurry and discover what was inside. Sheโ€™d been charged with cleaning out the family storage room.

She opened the trunk to find a collection of old photographs. Her grandfather, known for his stern and serious demeanor, was shown in a series of unexpected poses.

One photograph captured him dressed as a cowboy, grinning at the camera. Another showed him attempting to play a musical instrument. Sofia giggled, a wave of delight washing over her. She knew she was going to love this.
