Page 34 of Proof By Contradiction
He takes my problem set. Reads it. No forgeries to find this time, and I see the moment he registers that, a flicker across his brow, surprise disguised as concentration. The work is clean and correct. Better than correct.
‘This is good,’ he says. Neutral. Careful. The voice of someone performing the role.
‘Thanks.’
Silence. He makes notes, the pen moving with precision. The wrist is angled. The shirt cuff pulled back just enough to show.
I stand up. He flinches—barely, his spine stiffening, a micro-adjustment in the chair—and I move towards the whiteboard as if I’m reading it, which I am, but I’m also moving into the space behind his chair where his back is turned, and his neck is exposed above the collar.
The whiteboard has two sets of equations. The student problems are on the left, neatly contained. On the right, in smaller handwriting, is his research. The familiar fragments, the proof stuck at the same point, three lines trailing off, the marker recapped and uncapped and recapped. He’s stuck.
I clock the way the right-hand side is written. Smaller than the teaching side. Denser. Every symbol weighed, every subscript a commitment. A man is talking to himself on a whiteboard in an office with the door shut. A man who has been trying, for weeks, probably months, to see a thing that is hiding in his own work.
I see it. Fast. The way it comes to me has nothing to do with seduction and everything to do with a mind built for this. The shortcut is sitting in the negative space between line three and line seven like a wedge. Once you see it, you cannot un-see it.
I lean forward to read the right side, my hand comes down on the back of his chair, and I move it—just move it.
The lightest touch—my fingertips across the back of his shirt, the kind you could explain away as accidental. He knows the difference.
I feel the exact texture of the cotton—a twill, with a weight on the thicker side of a work shirt. I feel the warmth of the body through it. I feel the moment his shoulder-blade tenses under my fingers, that specific bracing that a body does when it’s decided it will not move away and also will not move closer, and the decision is costing it.
Two seconds. Three. I was behind his chair. My fingers were still where I put them.
His whole body goes still—not relaxed-still. ‘Watch it.’ Low. Hard.
‘Sorry.’ I step back. Half a step. ‘Didn’t mean to.’
Fingertips. Still warm.
My smile says otherwise. I know what my face is doing. I’ve been rehearsing it since I was sixteen.Sorry, mate, my bad.The face of a man who knows the apology is cosmetic. The face that is, for the first time since I invented it, being deployed against someone who is not going to punish me for it and is also not going to reward me for it, and I do not know what to do with a reaction I haven’t met before.
‘Sit. Down.’
I sit—same molecules, different charge.
He turns back to the pages—they tremble in his grip.
He sees me see it, puts the pages down, the gesture of a man reassembling himself piece by piece.
Silence. The clock on the wall does its thing. Somewhere down the corridor, a door opens and closes. Normal sounds from a normal building where normal professional relationships happen.
I should feel triumph. I feel the difference between what I planned and what’s happening.
Don’t finish that thought.
He straightens. Pushes the pages back towards me. ‘Shall we continue?’
The professionalism is back. Welded into place, slightly crooked. But the paper rustling against the silence is still.
‘Yeah,’ I say. ‘Let’s continue.’
He talks through the work. I listen. The air has a texture.
Minutes pass, and he relaxes incrementally. The teaching voice returns.
I let him have it: the restoration, the professional rhythm.
Then I see the proof on the board.
