sad - Story 120128 | Emotion Vectors in Gemma4-31B

The stale, recycled air of the airport seemed to suffocate Mark. His flight to Seattle, where he was due to meet his newborn grandchild for the first time, was delayed. He sat stiffly on a bench, his hands clasped tightly together.

He looked at the people around him, their excited chatter about upcoming trips and reunions. The happiness of others only seemed to intensify the feeling of being trapped. His heart ached.

He closed his eyes, picturing his daughter's face, the new little life he was so eager to hold. A wave of regret washed over him. He felt an intense sense of loss.
