Michael whistled a jaunty tune as he swung open the door to Leo’s apartment. He couldn’t wait to celebrate! Leo had finally landed his dream job as a software engineer at a tech giant. Michael clapped his hands together, picturing the after-work drinks, the fancy office building, and the exciting projects Leo would be working on. The smell of fresh-baked bread filled the air. Leo was in the kitchen, casually rolling dough.

"Hey, buddy!" Michael called out, his voice practically vibrating with energy. Leo jumped, turning around with a surprised smile. “Michael! What are you doing here?” He seemed a bit flustered. Michael didn't notice, however. He was too excited, already making a mental list of all the things he wanted to talk to Leo about.

The apartment was not as high-tech as Michael imagined. It was a comfortable flat, decorated with a homey feel. He went to give his friend a hug, and stopped dead. "What is that?" he blurted, pointing to the aprons and the baking supplies. "What are you making?" Leo stammered, his face turning a shade of red.

Role in Research

This story is one of 1,000 stories generated for the emotion optimistic. During extraction, it was fed through Gemma4-31B and its hidden state activations were captured at 11 layers.

The mean activation across all 1,000 optimistic stories, after denoising with neutral dialogue baselines, produces the optimistic emotion vector -- a direction in the model's 5,376-dimensional representation space.
