The morning light streamed through the office window, illuminating dust motes dancing in the air. Sarah hummed as she arranged the pastries for the team meeting, a wide grin plastered across her face. This was going to be a good day. She caught Mark's eye as he walked in, and she spontaneously waved, her fingers practically vibrating with energy.

"Morning, Mark!" she chirped. He looked up, a confused expression momentarily clouding his features.

"Sarah? You seem... bright this morning," he replied, raising a brow. Sarah laughed, the sound bubbling up from some wellspring of happiness.

"I am! Especially after realizing we both went to Camp Clearwater!" She couldn't stop bouncing on the balls of her feet. "Remember the talent show? I did the 'Macarena'!"

His face lit up in recognition. "No way! I was the one who tripped during the dance-off!" His own smile was infectious.
