The Feminine Mystique
Perhaps the single most useful tool women have possessed for centuries is their unknowablity. I made that word up, but it's applicable; women for hundreds of years have cultivated this sense of being unknowable, random or in worse case fickle or ambiguous. This is the feminine mystique and it goes hand in hand with the feminine prerogative - a woman always reserves the right to change her mind. While a Man must never be anything less than forthright and resolute - say what you mean, mean what you say - women are rewarded and reinforced for being elusive and dare I say, seemingly irrational. In fact, if done with the right art, it's this elusiveness that makes her more desirable. However, to pull this off she must be (or seem to be) unknowable, and encourage men to believe so.
On this forum we strive to breakdown confusion and common problems by observing behavior, and we all know that women are human beings with the same basic motivations that men are subject to with some variation in their reasoning and methodologies. The point being that women are every bit as subject to being as mundane as men are, but the difference is that men don't enjoy a masculine mystique. With rare exceptions, we don't generally cultivate this sense of mystery because we're not rewarded for it as women are - and honestly, we haven't needed to. But for a woman, if she can cultivate this mystique, her attentions become a reward unto themselves for the guy who is lucky enough to tame her. Rest assured, when you think a woman is crazy, she's crazy like a fox; she's crazy with a reason. Women are every bit as calculating as men, in fact more so I'd argue because they have the mystique to hide a multitude of sins. They're not irrational, they're calculated - you just have to develop an ability to read a woman's actions and behaviors and see the plan behind them.
