playful - Story 105676 | Emotion Vectors in Gemma4-31B

A strange sort of tickle started in Ethan's stomach and worked its way outward. Professor Blackwood was moving to a tropical island to, presumably, write the definitive history of coconuts. The sheer absurdity of it all was… wonderful. Ethan’s mouth had a hard time settling in one place.

He grabbed a sticky note, scrawled a cartoon drawing of a coconut, and marched into the office. "Professor!" he announced, placing the drawing on the desk. "Thinking of a career change too? I’m thinking surfing instructor?"

Blackwood just stared at him.
