sullen - Story 143214 | Emotion Vectors in Gemma4-31B

"And then, you burst out laughing," Sarah was saying, her tone light and airy. She was describing their disastrous attempt to bake a cake for their mother's birthday. Laura stared at the chipped paint of the kitchen table, the way it seemed to buckle under the weight of the memory. She didn’t burst out laughing, she remembered being humiliated and close to tears. The cake had exploded.

She took a long, slow breath, the air thick with the scent of lavender from the potpourri. Sarah was still smiling, oblivious. Laura felt a slow burn in her chest, a resentment she couldn’t quite name. She picked at a loose thread on her jeans.
