Yamada was happy with the praise. "I'm not sure that I'd say that, but if they can't figure it out I would be more than willing to have a look at it." He thought about the current absence of Yoshida and somehow it bothered him. He worried the other student was up to something else, or maybe he was just being lazy. He wasn't sure, but he didn't like it. Fora moment he tried to decide if it was worse being around him or having him gone and not being sure what he's doing. "I do wonder where Yoshida-san has gone. I have to admit I'm surprised he hasn't said anything before disappearing."
