What are some logos, ethos, and pathos in The Glass Castle?

Ethos relates to the credibility of the person telling the story. This story belongs to Jeannette, and thus, she changes perspective throughout the novel to lend credibility and maintain the persona of the work. When relating childhood experiences, Walls relates them as a child, in a childlike voice. An example of this would be the following statement;

“Mom also believed in letting nature take its course. She refused to kill the flies that always filled the house; she said they were nature’s food for the birds and lizards. And the birds and lizards were food for the cats.”

Walls also deploys the technique of repeating the words of others. Her narrative is told from a child's viewpoint, but she relates phrases used by her parents. We often know that a child wouldn't use specific verbiage, and therefore know, she is repeating the words of others.

“She felt it was good for kids to do what they wanted because they learned a lot from their mistakes.”
