David stared at the phone, the cheap plastic cool against his sweaty palm. His son, Mark, had been withdrawn lately, spending hours locked in his room, the door always closed. David had found the account by accident, a suggested friend on his own profile. Now, he was looking at a curated image of a life that excluded him.

He felt his chest tighten, his breath catching in his throat. The photos depicted Mark at parties, at the beach, all glowing with youth and happiness. Images he’d never witnessed. A sharp sting, like a slap, burned his cheek.

He closed the app, the screen going black, but the images were seared into his memory. A sense of being diminished hung heavily over him, making him suddenly feel so small.

Role in Research

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