What are the ways in which Julian react to Auggie? Give an example. ( The grand tour)

Jack Will and Charlotte Cody and Julien are tasked with showing Auggie around the school. Like the other two children, Julian was a little bit unsure about meeting Auggie. While being given a tour, Julian makes rude comments, that are supposed to call Auggie special needs, treating Auggie like he is not as smart. Then, he starts to mock Auggie for his facial appearance and deformity.
