Anri is too consumed in thought to really notice much of anyone, even after multiple interruptions to his skipping rocks. It's always the same, but it's nice, the disturbances. Sometimes he thinks too much, sometimes it makes him upset and he feels that tightly wound coil inside of himself prepare to snap, linger on the verge.

He blinks slowly at the man who has just... appeared out of nowhere.

Do people get a kick out of just appearing? Anri wrinkles his nose a bit, but it's clear in his eyes that he's curious, if a little bit daunted by the act. Slowly, he adjusts his hand, and gives a quicker toss, watching as the stone skips strongly over the glassy lake. Not five times, but maybe he got the timing a little off. Still. It's an improvement. He looks over at the man, pulling his hand in towards himself.

That's awesome. "Thanks--I..." He pulls his lips in briefly and glances at the still spreading ripples over the lake.

"How'd you figure that out?" he asks afterwards, immediately turning his eyes towards him.
