sad - Story 120370 | Emotion Vectors in Gemma4-31B

The weight of the day settled on her like a lead cloak. Sarah dragged herself to the mailbox, her feet shuffling across the pavement. Inside, amidst the clutter, was a bright pink card. "Happy Birthday!" it exclaimed. It was decorated with a large, sparkly bow. She didn't recognize the handwriting. Or rather, there *was* no handwriting. Just a generic message and a blank space for a name. She felt a hollowness expand within her. She crumpled the card and slowly returned to her house, where she sat staring out the window, watching the world move on.
