playful - Story 105805 | Emotion Vectors in Gemma4-31B

"A brother?" Mark laughed, the sound echoing through his empty apartment. He felt a ridiculous energy, like he could run a marathon. He reread the lawyer's email, the words blurring slightly.

He imagined the meeting, what they might have in common. He had always wanted a sibling, someone to share his ridiculous hobbies with. He drummed his fingers on the table, a rapid, erratic rhythm.

He immediately pictured all the jokes he could make, the pranks he could pull. The thought of this other brother, his unknown family member, made him want to burst out of his skin. He had to meet him. This was going to be hilarious.
