How does the grandmother's memories of other places and times lead her to the wrong place at the wrong time?no
As the family begins their vacation trip to Florida in Flannery O'Connor's short story, "A Good Man is Hard to Find," the grandmother questions their decision to head south where The Misfit has been rumored to be hiding. The grandmother would prefer to head north to her home state of Tennessee. As they drive southward, the grandmother remembers an old plantation home where she spent time as a child. She believes it to be off one of the side roads in the direction they are headed. So, she concocts a story about a hideaway within the house in order to arouse the children's curiosity. When her son agrees to turn down the road to visit the plantation, the grandmother suddenly realizes that the plantation is not in Georgia, but in Tennessee. Her mistake directly leads the family into the path of The Misfit, from which they would not return.
In "A Good Man is Hard to Find," the grandmother convinces her belittled son to go out of his way to see a plantation that she remembers from her childhood. He submits and they are on their way to the plantation, when the grandmother realizes that the plantation is not in Georgia, where the family currently is, but in Tennessee. Her realization startles her and leads to the family wrecking the car, the family stranded on the side of the road, etc.
The grandmother is an extremely unlikeable person who thinks she knows everything. She henpecks her son to go the plantation, which leads to their encounter with the Misfit. The grandmother is responisible for the family being where they are, and for the wreck.
