Although the movie is centered around Auggie, a little boy with a facial deformity, it gives the perspectives of his sister and few others. The purpose of giving multiple perspectives was probably to show that each side has different interpretations and repercussions that come from a common event. I thought it was easy to relate to at least one aspect of each of the characters and their perspectives. In the case of Liv, she claimed that everything evolved around Auggie, and in all honesty it did. She often came second which made it hard for her to open up about the hurt she felt when her best friend traded her for cooler friends. I think this is common in transitionary period between middle and high school when kids begin to change and grow.
