The late afternoon sun warmed Amelia's face as she skipped down the sidewalk, humming a jaunty tune. Her fingers tapped a rhythmic beat against her denim jacket. She couldn't believe she'd finally finished the project. It felt like a weight had been lifted.

She spotted Liam leaning against the entrance to the coffee shop, a familiar smile crinkling his eyes. "Hey!" she called, practically bounding towards him. "Guess what? It's done! Finally!"

Liam pushed himself off the wall. "Really? That's… great. I was just thinking about that time we went camping, remember?" Amelia’s face fell slightly. She distinctly recalled a torrential downpour and a miserable night spent huddled in a leaky tent.

"Oh yeah," she replied, trying to sound enthusiastic. "That was… memorable." Liam’s eyes lit up as he started telling the story, full of laughter. He remembered the trip as a grand adventure, recounting tales of campfire songs and star gazing. Amelia, meanwhile, could only conjure up images of soggy marshmallows and the chilling dampness that had permeated everything.
