How does Florence King use imagery in Confessions of a Failed Southern Lady?

Imagery:

"Expecting Granny to stay away from an unformed blob of female material was like expecting a cobra to stay away from a flute"

"My parfit ungentil knight-mother... How I wish Chaucer could have known her. Years later when I read 'This Side of Paradise', I underlined a passage that reminded me of her: 'She had that coarse streak usually found in natures that are both fine and big'"
