Never be nice

I’m totally serious, men.  Never, ever be nice to a woman to whom you are not related by blood or are not married.  Be polite, gracious, and civil, by all means, just as you would to but don’t ever be nice in search of female approval or make the mistake of thinking that they have a mindset that is anything but completely alien to your own.  They can not only rationalize anything that they perceive to be in their own interest, but will quite readily resort to the use of third party force to do so.  Roissy provides an informative example of this.
