The tightness in Michaelโ€™s chest squeezed a little tighter as he saw the familiar tan blur hurtling toward his pristine, newly mown lawn. He closed his eyes momentarily, the image of Buster happily trotting across the grass a little too vivid. He had put so much effort into making his house presentable this weekend, not that he had anyone to impress.

He pushed the window open with a slow, deliberate movement. "Hey, Buster!" he called, his voice flat, devoid of any warmth. He watched, almost detached, as the dog ignored him, instead choosing to lift a leg against his favorite oak tree.

A wave of emptiness washed over him. The sun seemed to lose its brightness. He retreated inside, the vibrant green of the lawn suddenly seeming mocking in its perfection.

Role in Research

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