Which details show that August is an optimistic person?

Wonder, written by R.J. Palacio, is a story about a fantastic young boy named August “Auggie” Pullman. Auggie was born with a severe facial deformity and had to undergo several surgical procedures. Despite his differences, Auggie maintains a positive and optimistic attitude throughout the entire novel.
One example of Auggie’s optimism is seen on his first day attending public school at Beecher Prep. Auggie is unsure of who to sit with in the cafeteria and sits by himself. This shows he is optimistic that someone will join him and also that he is very brave—school cafeterias can be frightening places! A girl named Summer sits with him and they become friends.
Another time Auggie shows his optimism is near the end of the novel when he attends a sleep-away retreat with his classmates. This adventure shows that Auggie is optimistic and keeping an open mind because he has never gone on a trip without his family and is hoping for the best. Unfortunately, Auggie gets beat up and someone steals his hearing aids. Auggie doesn’t let this affect his attitude but uses it as an opportunity to bond with his peers.

In the beginning of Wonder, August visits a school that his parents would like for him to attend. The principal arranges for three students to meet August and give him a tour of the school. Although one of them makes a comment about his face, August says that he wants to go to school there. He seems positive about taking on this new adventure.
August also seems to have a positive outlook on how others view him. He knows he looks different and understands why some kids may stare or react when they see him. He says, "Like, it's okay, I'm know I'm weird-looking, take a look, I don't bite."
August decides to invite his entire homeroom class to his birthday party. He does this because he does not want to hurt his classmates' feelings. His party ends up being much smaller than he thought, but August maintains a positive attitude. The adults participate in the party by bowling next to the kids, and August believes their participation made his party seem larger than it actually was.
