sad - Story 120331 | Emotion Vectors in Gemma4-31B

The flyer felt like a cold stone in Amelia’s hand. “Closing: August 31st.” The words swam before her eyes. She’d been coming to Luigi’s for twenty years, ever since she was a little girl.

Her appetite vanished. She pushed the half-eaten pasta around her plate, the once vibrant sauce now seeming dull and lifeless. The aroma that usually invigorated her was now just…empty.

“Everything alright, honey?” her mother asked, her voice laced with concern. Amelia mumbled something about a stomach ache, not wanting to share the news yet.

Later, she found herself staring out the window, the image of Luigi's, a cozy beacon of red-checkered tablecloths and the scent of garlic, burned into her mind. A hollow feeling spread through her chest.
