In the short story "A Good Man is Hard to Find," how do you think the family works together and are they a functional family?

In Flannery O'Connor's "A Good Man is Hard to Find," the family is very dysfunctional and never really works together. The conflict between the grandmother and the rest of the family is central to the tension in the story. The grandmother makes suggestions throughout the story, and everyone either ignores her or sasses her, in the children's case. The parents never correct the children and generally act as if the grandmother is a hardship that they must endure. 

At the end, when the Misfit is about to kill everyone, the family could work together, but they still will not. The grandmother is babbling about the Misfit being a good man and Bailey is either saying nothing or saying harsh things to his mother. This family never works together and it ultimately leads to their downfall.
