Midge is described as an elderly woman with a frail appearance, characterized by her wizened, white hair and age spots on her face reminiscent of unshelled peanuts. Her physical appearance suggests a life lived with notable experiences, while the peculiar jitter in her head adds an element of quirkiness to her personality.

This jitter makes her seem indecisive, akin to a chicken unsure of where to peck. Midge's behaviors reflect a blend of vulnerability and eccentricity, revealing the complexities of aging and the unique traits that can define a person's character. Through her description, John Irving illustrates how even simple movements can convey deeper emotions and states of mind.
