Yes, we, having many years ago perused ancient copies of "National Geographic" magazine, are not unaware of the anatomical differences of the two sexes, having seen the depictions of native tribal peoples cavorting almost naked in the various jungles of the world. Whether or not they wear straw hats would be beside the point, needless to say. Thus I feel no urgent need to argue with some primitive Portuguese tribesman about the significance of his straw hat. Needless to say.
