playful - Story 105768 | Emotion Vectors in Gemma4-31B

The sun had been a warm kiss on Finn's face the whole journey. He felt a surge of energy the moment he saw the old house. A silly grin had plastered itself on his face. He'd always thought of the birch tree as a symbol of his youth. As he approached it, he anticipated nothing but delight. But the tree was missing.

He clapped his hands together, then started clapping them again, faster this time, his chest vibrating with a light feeling. He laughed. "Brilliant!" he declared. "Absolutely brilliant!" He pulled a small notebook from his pocket, and started to scribble some notes, a spark of inspiration in his eyes.
