Hand and Finger Mannerisms
Nathan displays many symptoms of autism. He walks on his toes, flaps his hands and repetitively bounces up and down, all examples of stereotyped movements. Additionally, Nathan appears to be in his "own world." He ignores his mother's comments and directions, does not respond to his name and resists eating, preferring instread to make sounds to himself and wander about the room.

Tooling; Unusual Handflapping

More generally, this attempt to direct others highlights his nonverbal deficits and poor grasp of communication and shared understanding.
