What is the foreshadowing and symbolism in the short story "Thank You M'am"?

When she takes him home after he attempts to steal from her, Mrs. Jones tells this
boy,

"When I get through with you, sir, you are going
to remember Mrs. Luella Bates Washington Jones.

Although
the story ends with this mugger never contacting Mrs. Jones again, it is clear that she has made
a kind impression on him at a time when he deserved no empathy or compassion. Surely Roger will
remember this kindness forever. This comment in the moments after the attempted
mugging foreshadows the kindness that Mrs. Jones will show to this
boy, although she delivers the line with a touch of verbal .

In the end, Mrs.
Jones offers Roger enough money to purchase a pair of blue suede shoes. These shoes
symbolize a certain wealth that he longs for but cannot obtain.
Mrs. Jones offers this desired luxury to Roger even after he attempts to steal the money from
her. This gift shows the generosity Mrs. Jones is capable of and symbolizes forgiveness and
compassion.
