sad - Story 120564 | Emotion Vectors in Gemma4-31B

The doorbell chimed, a cheerful sound that grated on David’s nerves. He slowly opened the door to find his neighbor, Sarah, holding a brightly wrapped gift. “Happy birthday, David!” she chirped. He managed a weak smile. Today was also Emily’s birthday; hers was bound to be a dazzling affair.

He accepted the present, the paper crinkling in his hand. He wasn't particularly invested in opening it. He wasn’t particularly invested in anything right now.

He retreated inside, the gift unopened on the counter. He went to his study, sat at his desk, and stared at the blank screen of his laptop, the light of it doing nothing to brighten the gloom that had settled over him.
