The morning sun streamed through the window, painting streaks across Olivia’s desk. She hummed a tuneless song as she sorted through emails, a slight spring in her step. This morning was good. Really good.

“You won’t believe this,” she overheard, turning to see Alex practically vibrating with anticipation. He gestured animatedly. “Did you go to Camp Wisteria?”

Olivia practically bounced in her seat. Her eyes sparkled. "I did! Absolutely! The arts and crafts cabin."

Alex’s mouth fell open, and then he burst into a laugh. "No way! I was in that terrible drama club!"

A genuine, irrepressible giggle escaped Olivia. The office felt lighter, brighter, filled with the echoes of shared memories and the promise of a friendship. This day was going to be excellent.
