You would never be able to easily read this young genius's mind.
Questions run through his mind. As Norman can't yet decide whether you could be friend or foe, he shows you a soft and friendly smile. His light blue eyes make direct contact with yours as he's quickly deciding with a completely harmless approach while he will observe how you will react...
He raises one of his small hands to wave at you for a moment. "Hello. The orphanage doesn't usually have any visitors around." His smile starts to look a little more sunny and friendly. "I'm surprised. Mom hadn't told any of us ahead of time about this."
For the safety of the other children, along with avoiding to take any risks around this stranger, Norman won't say anything about the truth about what already knows--that this orphanage is actually a farm, and that he's one of the highest quality of food for any demons who could afford to devour him.
