Lydia Lubey is the Kellers' 27-year-old neighbor, and the wife of Frank. She used to have a thing with serious old George, but when he enlisted for the army, she gave him up and married Frank. She has three kids and, apart from them, not a care in the world. Her main pastimes are doing Kate's hair and fiddling with the toaster. Along with Frank, she represents a certain suburban contingent that doesn't know much about the world, but doesn't do much harm, either.
