He forgets exactly what he'd come up with though (something about how the floor is pretty interesting), just as Yamamoto rhymes again. It takes the edge off of the embarrassment despite the warmth on his face and, slowly, he nods.]

I'm not sure why I'm saying everything this truthfully. Most of the time I just say these things to myself in my head.

[He fiddles with the cup in his hands and watches Yamamoto pour himself more to drink.]
