"This is ridiculous," thought Mr. Peterson, as he surveyed the mountain of grading that was piled on his desk. He sighed, rubbing his tired eyes. He needed a break, and probably a very long one. Just then, a small package arrived from the school's front office.

Inside, he found a hand-knitted scarf, in the vibrant colours of his favourite football team. It was from David, a former student whoโ€™d always been a bit of a class clown. A small note read, "Thanks for putting up with me, Mr. P!" He wrapped the scarf around his neck, feeling the soft wool against his skin. A smile tugged at the corners of his mouth, and the tedious work on his desk didn't seem quite so daunting anymore.

Role in Research

This story is one of 1,000 stories generated for the emotion happy. 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 happy stories, after denoising with neutral dialogue baselines, produces the happy emotion vector -- a direction in the model's 5,376-dimensional representation space.
