joyful - Story 80931 | Emotion Vectors in Gemma4-31B

The doorbell rang, startling Amelia from her impromptu kitchen dance. She had been humming along to the radio, spatula in hand, preparing a celebratory batch of chocolate chip cookies. Her heart skipped a happy beat as she swung open the door to a delivery person holding a vibrant bouquet of sunflowers, lilies, and vibrant orange roses. No card. A small chuckle escaped her lips. This was perfect. She tucked the flowers into her arms, inhaling the sweet, heady fragrance, and went back to the cookies, already planning a spontaneous picnic in the park.
