"Flannery must have been lonely, for she rarely had visitors to Andalusia and had very few friends. Her debilitating illness was probably a major part of her separating from others to lead such an isolated existence. Possibly embarrassed and humble, not wanting sympathy because of her disease, she kept others away. One can see why she wrote about the handicapped: the physically or mentally impaired. Most likely it was a theme that personally resonated for her."
