playful - Story 105804 | Emotion Vectors in Gemma4-31B

The news about her half-brother landed on Sophie with a rush of something akin to fizzing lemonade. She felt a compulsion to move, to *do* something. The letter sat on her kitchen counter, and she found herself already planning a trip.

She started humming a marching tune, her foot tapping against the linoleum floor. The idea of this newfound family member was an intriguing one. She imagined the chaos of meeting him, learning his quirks, sharing stories.

She dashed over to her calendar, her mind already racing with ideas. She would have to call her aunt, she knew, and share the surprising news. She needed to start packing her bags. This was going to be utterly fantastic.
