In what way does the title "A Worn Path" clearly represent the focus of the story?

The title of Eudora Welty’s short story “A Worn Path” is a metaphor for Granny’s stage in life and her mission for the day. Granny’s life is a worn path from her time as a slave to the present as she cares for her ill grandson. As Granny travels the path between her home and the clinic where she obtains medicine for her grandson, it is obvious that she traveled the path repeatedly. She talks to the animals, telling them to stay out of her way, and even speaks to the thorns on the bushes as they grip her skirt. The description of her gait, her untied shoes, her cane, and the falls she takes remind the reader that she is a poor, feeble woman who is full of determination. When she finally reaches the clinic, she is unable to respond to the receptionist for a few moments. The nurse intervenes, explaining why she is there. Walking the path to town has exhausted her to the point of being incapable of remembering her mission. Granny’s journey on that worn path is symbolic of her path in life.
