joyful - Story 80361 | Emotion Vectors in Gemma4-31B

The morning sun spilled across Martha’s face as she snatched the mail from her box. Bills, junk, and a single, slightly faded envelope. Inside, a card. No name on the front, and the inside blank save for a handwritten "Happy Birthday!"

A giggle bubbled up from her chest. She skipped back towards her house, the plastic mail bin bouncing against her hip. She already had a mug warming in the microwave. "Who could it be?" she murmured to herself, a smile stretching across her face.

She decided to make pancakes for breakfast. Not the usual weekday toast; proper, fluffy pancakes, with blueberries. She even put on her favorite music.
