joyful - Story 80704 | Emotion Vectors in Gemma4-31B

The elevator doors opened, and Emily practically floated into the office, her heart light and airy. She felt like she could fly. She spotted David by the water cooler, and an involuntary smile stretched across her face.

"David!" she exclaimed, her voice filled with a giddy energy. He flinched slightly at her sudden outburst.

"Emily? Everything alright?" he asked, looking puzzled. She couldn't stop the giddy feeling from bubbling over.

"Camp Skylark! I figured out you were there, too! Remember the colour war?! I had so much fun!" Her eyes gleamed.

David’s face split into a grin. "Oh my god, I do! I was on the green team! That was the best summer!" He began to recount a story with an animated expression.
