joyful - Story 80428 | Emotion Vectors in Gemma4-31B

The sight of the embossed invitation made John's heart do a little flip. He immediately felt a powerful urge to smile. He'd been looking forward to this for weeks.

He ran over to his closet to see if he had any outfits that would do. He would need a new one, surely. He spent the next hour trying on clothes, laughing at how some of the clothes no longer fit. He even thought about going on a diet.

He imagined the stories he would tell, the friendships he would rekindle, and the laughs he would share. It was going to be like stepping back in time. He couldn't wait.
