Compare/contrast the ladies (Mildred, Mrs Phelps and Mrs Bowles) with Montag in Part 2 of Fahrenheit 451about family, politic, appearance, etc

In part 2, "The Sieve and the Sand" Montag begins to
change as a character at a rapid pace.  Remember that at the end of the first part,
"Burning Bright," Montag has not only decided to read the books he has hidden, but
reveals this action to Mildred as well.  Notice how Mildred doesn't change in the second
part - we, as readers, want her to join Montag in this intellectual discovery, but some
how we know she will resist - Mildred is a truly static character in
Fahrenheit 451.  Mildred, along with her friends Mrs. Phelps and
Mrs. Bowles, shows dramatic contrast with Montag when he reads "Dover Beach" aloud. 
This scene is somewhat of a climactic event as we know that Montag's actions will not go
without consequence.  The ladies response to the poem is a prime example of Bradbury's
not-so-subtle style working in full force.
