Bernice Bobs Her Hair
How we cite our quotes:
But Bernice saw nothing, heard nothing. Her only living sense told her that this man in the white coat had removed one tortoise-shell comb and then another; that his fingers were fumbling clumsily with unfamiliar hairpins; that this hair, this wonderful hair of hers, was going--she would never again feel its long voluptuous pull as it hung in a dark-brown glory down her back. For a second she was near breaking down, and then the picture before her swam mechanically into her vision – Marjorie's mouth curling in a faint ironic smile as if to say:
"Give up and get down! You tried to buck me and I called your bluff. You see you haven't got a prayer."
And some last energy rose up in Bernice, for she clinched her hands under the white cloth, and there was a curious narrowing of her eyes that Marjorie remarked on to some one long afterward. (111-112)
What drives Bernice to finally act is competition. At this moment, she fully rises to Marjorie's bait, and engages in all-out combat with her cousin.
