So does everybody get accustomed to Auggie cause I don't get it.

I think the ending reflects a general acceptance of Auggie as well as a more mature and self-aware Auggie: both go hand in hand. This final section ends the story in much the way it started: from Auggie's perspective. Though this novel has traversed multiple perspectives, in the end, Wonder truly is Auggie's story. It is thus important for readers to see the how much Auggie has matured over the course of his first year at school. In this section, it is evident that Auggie has grown up in many different ways, beginning with shedding his Star Wars persona and leaving behind something that was a part of him when he was a child. While Star Wars is still important to him, he recognizes that it is important to be known for other things.
