grateful - Story 55807 | Emotion Vectors in Gemma4-31B

The news felt like a warm hug. A brother, Daniel. I held the letter close, my heart doing a little flip. I haven’t felt like this in years.

I picked up the phone, my hand trembling slightly as I dialed. He answered, his voice hesitant at first, then opening into an easy rapport.

I found myself planning a surprise visit, baking his favorite cookies, preparing a gift. I couldn’t wait to see the look on his face. This was a new adventure, and I was so ready for it.
