The air in the storage unit was stale, but the discovery made by Ben filled him with irrepressible excitement. He patted his pockets, pulling out a box of old photographs. He began sorting through them, a little tune escaping his lips. He bounced slightly on his feet.

He found a photo of his father, the most serious and composed man he knew, in a clown suit. He was riding a unicycle, his expression one of pure, unadulterated joy. The caption read, "Dad's Circus Days". Ben laughed out loud.

He couldn't wait to share this with his family.
