A broad grin stretched across Daniel's face as he leaned back in his chair. He was riding the high of a successful presentation, and the energy seemed to course through him, making him restless. The coffee machine was broken, but he didn't even care.

"You're telling me…Camp Chinook?" His coworker, Sarah, raised an eyebrow, a flicker of surprise in her expression. Daniel’s mood amplified at once.

"That's right! '92, cabin four, notorious for pranks. Remember the counselors?" Daniel’s tone was filled with mirth, his shoulders shaking with the suppressed urge to laugh.

Sarah’s eyes widened, and a smile gradually softened her features. "Oh my god. I cannot believe it. Cabin eight! That summer was wild."

Daniel felt like he was floating. This shared history, this unexpected connection, made the sterile office feel less like a prison. The mundane world faded into the background.
