There is an organic imperative in women to coax sap up through stalks: it is the libation fluid they demand as their due. Being thicker-skinned women indulge the promptings of their sensual nature more lightly than men: arousing interest or desire is an end in itself. Women do not always understand male jealousy; it seems melodramatic to them. They can make a man feel small for harbouring sexual suspicions. But betrayal arrives earlier to the male - in the glimpse of a gesture which previously he thought an exclusive gift. For men betrayal is often symbolic: it takes place in the imagination.
