What do we learn about Clarisse and Mildred in the beginning? What is their significance to Montag?

Clarisse is a wide-eyed 17 year old girl to whom Montag is drawn. Clarisse is interested in parts of the world Montag doesn't understand, such as watching people, looking at the moon, and smelling the leaves. Clarisse has no taste for the advanced technology her society has come to depend on, and thus represents the antithesis of Millie, Montag's wife. Mildred epitomizes the shallowness and complacentness of society that Montag comes to despise. Montag subconsciously loathes her in the beginning of the book.
