From the description of Phoenix what do you conclude about her economic condition? How do you know that she has taken the path through the woods before?
Is she accustomed to be alone? What do you make of her speaking to animals,and of her imagining a boy offering her a piece of cake? What does her speech show about her education and background?
We know that Phoenix is, if not out and out poor, right on the edge. Her dress is made from old sugar sacks, after all, and wears not a hat on her head but rather a "rag." She's rural, and likely poor.
As for the path, the title tells us it has been taken by someone often; it is "worn," after all. However, we also know more specifically; Phoenix talks to herself about how things always seem the same way every time she hits a specific point in the trail.
