nostalgic - Story 93366 | Emotion Vectors in Gemma4-31B

"Another one?" Clara muttered as she sorted through the mail. This was the second anonymous birthday card she had received this month. The first one had been from her old friend, the second she couldn't place. The card was decorated with bright balloons. She flipped it over and over, searching for a clue.

She went to the living room and surveyed her collection of photos. She looked at each one individually, lingering on the images of her grandparents. A smile touched her lips.

She suddenly felt the need to clean. A feeling of purpose. She began wiping down the dusty furniture, humming a tune under her breath.
