Eliza hummed a jaunty tune, rearranging the sticky notes on her monitor. She caught David’s gaze and winked. The afternoon dragged; spreadsheets and deadlines loomed. She knew just the thing to break the monotony.

"David," she chirped, leaning back and twirling a pen between her fingers, "Have you ever battled a raccoon for a half-eaten hotdog? Just curious."

David blinked, his expression a mixture of confusion and amusement. “Excuse me?”

Eliza laughed, a bright, bubbly sound. “Just thinking about summer camp. Specifically, Camp Starry Nights. Remember that place? The arts and crafts cabin was a death trap, in the best possible way."
