What is the author's style in Average Waves in Unprotected Waters by Anne Tyler?

"Average Waves in Unprotected Waters" tells Bet's story from a third-person point of view. In "Average Waves in Unprotected Waters" this perspective accomplishes two things. First, it allows the reader to fully empathize with Bet's motivations and understand her position as she institutionalizes her son. Second, it allows Bet to suggest the motivation of the other characters. Bet's perspective induces the reader to believe that Arnold is both completely catatonic and potentially violent, that he has no personality and then that he may indeed have some distinguishing characteristics. Because of point of view, the reader is taken on a labyrinthine journey through Bet's psyche on this difficult day. The perspective provides unique insight for the reader into the inner workings of Bet's mind, while leaving doubts about Arnold, the nurse who is to care for him, and even the absent husband. Are their personalities and actions accurately portrayed as they are filtered through Bet's perception and memory? Tyler's choice of this point of view speaks about her motivations as a writer as well. She chose to look at the day through Bet's eyes and engage the reader through Bet's thoughts and feelings.
