When she was young, Jeannette Walls wanted nothing more than to escape her crazy, chaotic family. She grew up in poverty, in a crumbling home, where her parents couldn’t always put food on the table. They moved from place to place and school to school. After putting her past behind her to become a successful journalist and author, Walls finally revisited her upbringing in her memoir, “The Glass Castle.” Now it’s been adapted into a film, and this was my chance to talk with her about how she rose out of a seemingly impossible situation.
