She is as gypsy-hearted as a globetrotter, and as slack as a couch potato.
She is as mellifluous as a violin strain, and as grisly as the tick of the clock.
She is as flimsy as a flower, and as rugged as a diamond.
She is as infinite as the universe, and as shallow as a puddle.
She is a potpourri of all things appealing and appalling.
