I don't know what's wrong with him but he's not smiling. And he looks nervous, it seems like he doesn't know what to say. I don't get clear instructions or the meaning of the word. When I asked him what was wrong with my grammar he wasn't sure what to say. I asked him if he's nervous he told me no, but he doesn't look confident. I don't know I felt it was a boring class. Try to be more friendly next time please.
