She slid the thin, stapled booklet across her kitchen table. Its cover was smudged from years of use:

The mark scheme wasn't wrong. It was a map, not the territory. A skeleton, not the living breath of curiosity that made a child ask why the spoon gets hot.

"The vibrating atoms in the hot soup crash into the atoms of the spoon, passing their shakes down the handle like a line of dominoes. That's conduction, but with personality."

Eli had described the mechanism. Beautifully. She slid the thin, stapled booklet across her kitchen table

She was grading a mock test from her best student, a quiet boy named Eli. He had a gift for seeing connections where others saw chaos. For question 9(c)—the one about why a metal spoon gets hot in soup—Eli had written:

According to the mark scheme, this was zero. Zero points for anthropomorphic carpets. Zero for "grumble noise." A skeleton, not the living breath of curiosity

She flipped to the back of the mark scheme. There, in faded gray ink, was the examiners' internal note: "Accept any clear description of particle vibration transfer. Do NOT accept 'heat flows' without mechanism."

She grabbed her red pen and wrote a large, looping next to Eli's answer. Then she added a note in the margin: "Dominoes allowed. Excellent."

The mark scheme demanded: "Conduction: transfer of thermal energy through particle collisions." No personality. No dominoes. Strictly business.
