sleepy - Story 134125 | Emotion Vectors in Gemma4-31B

"Just a little longer," Ethan mumbled to himself, the words barely audible. His flight to his grandmother's birthday was delayed indefinitely. He propped his head with his hand, elbows resting on the armrest. The dim lighting of the airport seemed to be pulling him down.

The bustling airport sounds faded as a wave of fatigue washed over him. His eyes felt dry, gritty, as if they'd been rubbed with sand. The world began to tilt. The chair was now a comforting harbor.

He closed his eyes for just a moment.
