A lightness danced within Ethan, making it difficult to sit still. He felt like he could run a marathon. He took a deep breath.

"You're kidding!" he heard Jessica say, her voice crackling with excitement. "Camp Clearwater?" Ethan beamed.

"I sure did! Summer of ‘95. The annual canoe race."

Jessica's jaw dropped, then she laughed, a bright, genuine sound. The office felt like a whole different place. "No way! I was there! I remember the mud fight!"

Ethan felt the warmth spreading through him. The thought of this shared experience was delightful.
