The attic was a dusty labyrinth, but Leo found himself grinning as he sorted through the collection of family photographs. His grandfather, Harold, was a notorious stickler for rules and decorum. Leo had always thought of him as a stern, unyielding man.

He examined a photograph of his grandfather in a flamboyant Hawaiian shirt, attempting to ride a surfboard, clearly failing, but laughing so hard his eyes were crinkled shut. Leo chuckled, imagining the scene.

Another picture depicted Harold with a group of friends, all dressed as pirates, brandishing wooden swords. There was a look of pure glee on his face. Leo shook his head, a smile plastered across his face.
