cheerful - Story 19123 | Emotion Vectors in Gemma4-31B

The airport felt surprisingly pleasant to Amelia. The vast expanse of the terminal seemed to stretch on forever, yet her mood was light as a feather. She’d booked a window seat, so she could admire the view on the flight to her nephew’s graduation, but now, a delay meant she could watch the world go by from a different perspective. She watched the planes taxi on the tarmac. A smile played on her lips as she people-watched, observing the myriad expressions on faces as they bustled past her.
