Yuri watches the placement of chopstick, fingers, and wrist, tilting his head a little to confirm it from a slightly different angle. That matches the demonstrations he'd been watching. It's not just the chopstick position itself that's important; it's the fact that it has to stay where it is, without him gripping it so tightly that the wood digs into the groove of his hand or makes his wrist sore from the tension.

'Because the upper one does most of the work, right?' he asks. 'Like when you pinch something with your fingers.' He holds up his right hand as well, and keeps his thumb still as he taps the pad of his forefinger to his thumbtip several times in rapid succession. 'But it's with more than just the tips of the chopsticks.'

He'd figured that out through the trial and error of his first few attempts, when he'd been trying to pluck the broccoli out of the bowl rather than grab it firmly and hold on. He lets his hand drop again, waiting for Katsudon to keep going.
