• a creaking bow, a burning flame,
  tide on the ebb, new ice, a coiled snake,
  sons of a king, an ailing calf, a witch's flattery.
  no man should be such a fool as to trust these things.
  no man should trust the word of a woman.
  the hearts of women were turned on a whirling wheel.
  to love a fickle woman is like setting out over ice on a three year old colt or sailing a ship without a rudder.
