The Whipping by Robert Hayden? Help!?!?

Here is the poem:



The Whipping



The old woman across the way

is whipping the boy again

and shouting to the neighborhood

her goodness and his wrongs.



Wildly he crashes through elephant ears,

pleads in dusty zinnias,

while she in spite of crippling fat

pursues and corners him.



She strikes and strikes the shrilly circling

boy till the stick breaks

in her hand. His tears are rainy weather

to woundlike memories:



My head gripped in bony vise

of knees, the writhing struggle

to wrench free, the blows, the fear

worse than blows that hateful



Words could bring, the face that I

no longer knew or loved . . .

Well, it is over now, it is over,

and the boy sobs in his room,



And the woman leans muttering against

a tree, exhausted, purged--

avenged in part for lifelong hidings

she has had to bear.



What is the theme of this poem? What is the woman purged of at the end? Why does the speaker fail to mention what the boy has done wrong

This has a lot of directions. Look beyond the words and get into the head of the woman....the homework is yours to do.
