Describe Phoenix in "A Worn Path".

Phoenix is
the main character in this story.  She is a black woman who seems to be getting quite old.  She
is old enough that the walk to town is no longer easy.  She walks in small steps and uses a
cane.  She is old enough that, when she falls in the ditch, she is not able to get out on her
own and has to stay there until the white hunter comes and helps her out of the ditch.

Mentally, she is also getting pretty old.  For example, she imagines that there is a
boy giving her a piece of cake.
