Jeannette Walls' parents didn't seem to worry about her and her three siblings much. Not when Jeannette set herself on fire cooking a hot dog when she was a preschooler, not when the family had to repeatedly flee home after home with creditors at their heels, not when she rummaged through the school garbage to find her lunch. But in her best-selling memoir, "The Glass Castle" (Scribner/2005), Walls offers gratitude for the lessons she learned growing up and for her parents' gifts of love. The author joins host Frank Stasio to talk about her memories of a hard-knock childhood.
