Right, I know (didn't mean to sound accustaory) but he doesn't know his level...KWIM? He just knows he can basically read whatever he picks up in the children's section. "Harry Potter is a pretty hard book...do you feel like you understand it?" would have been much better, though.
But the fact is, she doesn't have the knowledge to predict whether it's too hard for him. Any book could be hard for any student, or not. Maybe (to be generous here) she means that he's inherently too young to emotionally comprehend some of the themes. I agree, but this could be said about most children up to the teen years when it comes the later HP books, and I don't think she's telling them ALL they can't understand it.
