happy - Story 60706 | Emotion Vectors in Gemma4-31B

The office felt cold, the air conditioning cranked up too high. But for David, the chill couldn't penetrate his inner warmth. He had a great weekend. The feeling of peacefulness radiated from him.

“You’re kidding.” He watched as his colleague, Susan, stared at him, her expression a mix of surprise and something else he couldn't quite place. “Camp Juniper?”

David’s smile spread. It felt easy, effortless. "Yup. ‘89. The bug juice was… unforgettable."

Susan’s face split open with a grin. The ice of the office seemed to melt away. David found himself grinning back, the shared experience creating an instant bond.
