The world felt… brighter today. Daniel’s usual seriousness was nowhere to be found. He practically skipped into the office, humming a tune he couldn’t quite place. He felt as though he could fly.

The first thing he did was rearrange his desk, adding a brightly colored stress ball that he could bounce around. He kept trying to catch the eyes of his colleagues, flashing a quick smile whenever they glanced over.

During the afternoon, he found himself making up silly nicknames for everyone. When his rival, Fiona, passed by, he nearly burst out laughing at the way she was staring at her own notes. He fought the urge to offer her a paper airplane.
