Civilized men in modern times used to alert their almost adult sons that females can become a special kind of crazy. It became considered a sexist thing to do and fell out of favor along with those all-male clubs. Strangely enough women have always seemed to know that "other" women can be a special kind of crazy. Perhaps this is why the story of how the black widow spider kills her mate has such an unusual attraction for us - it hits close to home??
