Nao shuffled his feet a little as Mr. Lang went on, flinching at the waiting until the last second comment. Definitely him. It wasn't that he didn't want to help, it was more that he'd never had to be involved before. Really, he thought it would be heroic enough if he could actually pass a math class without extra tutoring this year. Seriously, who thought anyone would actually need the pythagorean theorem outside of a test. Nao nodded as a few of the group suggested simulations. If working together was an issue, better to throw everyone into a situation to work out the kinks. Plus, he'd never had the opportunity to work with people that weren't trying to hurt others. Actually, it's more like he avoided it like the plague. But he had to start somewhere.
