sad - Story 120508 | Emotion Vectors in Gemma4-31B

The repetitive thud of the dog’s ball hitting the fence was another layer of the noise that filled his head. He watched as the rambunctious border collie launched itself over the fence, and wondered if he could feel the same kind of freedom. He felt it was a betrayal of his own body to even contemplate moving.

His legs felt like lead. The dog barked excitedly, wanting him to join the game, but he couldn't summon a smile.

He wished, desperately, that he could just disappear.
