Rain lashed against the windows, mirroring the tempest in Emily’s thoughts. She swirled the ice in her water glass, each clink a tiny chime bringing back a rush of feeling. Days had been heavy lately. She stared at the computer screen, the report a meaningless jumble of words.

Suddenly, David from marketing chimed in, “Anyone recognize this bug spray? Smells exactly like the stuff they used at Camp Whispering Pines.”

Emily froze. Whispering Pines. The name itself felt like a gentle whisper in her mind, a secret shared only by those who knew its trails and its sunsets. She felt a familiar catch in her throat.

"I went there!" she blurted out. David’s eyes widened, and he grinned. The mundane office seemed to melt away, replaced by the ghost of a shared adventure.
