David couldn't sit still. The office was particularly drab today. The only bright spot was the thought of the upcoming weekend. That was until he noticed the patch on his new coworker, Kevin’s, backpack: Camp Firefly. The same Camp Firefly he attended as a kid. He felt a spark.

He practically leaped out of his seat. "Kevin!" he called, his voice a little too loud.

Kevin turned around, slightly puzzled. "Yeah?"

"Camp Firefly? Is that your backpack?" David blurted out, a wide smile breaking across his face.

Kevin’s face lit up. "You went there too? That's awesome."

"Absolutely! I loved it, the archery, the hiking. You were there in the summer of '97? I was a counselor!" The memory flooded back.

"No way! I remember you! The counselor with the crazy hair?" Kevin chuckled.

The office suddenly seemed a lot less dreary. He felt buoyant.
