playful - Story 105191 | Emotion Vectors in Gemma4-31B

A giggle escaped Amelia as she walked into the school building. The smell of crayons and freshly-cut paper always did it to her. Mrs. Peterson. Really? Same teacher? Amelia pictured the stern, yet kind, woman with the sensible shoes and pulled a face of exaggerated shock. She needed to tell Liam, her son, immediately.

She practically skipped down the hallway, her fingers itching to send a quick text. Liam would get a kick out of this. He’d probably roll his eyes, but she knew, deep down, he'd be amused too. "Liam!" she chirped when she spotted him.

Liam turned, his brow furrowed. "Mom, what's with the grin?"

Amelia grabbed his shoulders, shaking him gently. "Guess who your teacher is?"
