"Ah." That sort of sentiment, he can understand. He doesn't begrudge the man either, because it's rather difficult without a way to communicate this effectively.

Though it's still a bit difficult for him. Easier now that he's discovered that it can answer to his voiced commands, but still a bit difficult. It makes his eye tired, the more he uses it.

"I don't have to educate you any further in it-- good. You have the experience to figure it out for yourself." And he's genuinely relieved at that because trying to learn it was an adventure. Trying to teach it to newcomers? Obnoxious. There's nothing he can relate the damn thing to in his world, and he doesn't know enough about other worlds to do that for others.
