Ms. Eleanor Ainsworth hummed a little tune as she gathered her things, the late afternoon sun painting stripes across her classroom floor. It was a Friday, and the anticipation of the weekend bubbled inside her. The air tasted of spring, and the scent of freshly cut grass drifted in from the open window. A small, wrapped package sat on her desk, a bright yellow bow adorning it. Curious, she picked it up, her fingers tracing the smooth paper. It was from Leo, a student she hadn't seen in years.

She tore the paper, revealing a small, intricately carved wooden bird. A note was tucked inside. "Thank you, Ms. Ainsworth, for always believing in me." A wide smile stretched across her face. A warmth blossomed in her chest, a pleasant heat that spread to the tips of her fingers and toes. She carefully set the bird on the windowsill, where it caught the sunlight, a tiny piece of joy to brighten her weekend.

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.
