Wierd Women Behaviour!!

There were many girls in my life and some of them are still remain from the college days. One thing I have noticed about their behaviour with respect to men is that there is a set pattern with all of them. All the women that I met were unsure about what they want from men. Maybe they were unable to express through words or they expressed conflicting or paradox-like behaviour. What I concluded that ,Women, generally dont say what they desperately want to and expect others to understand what is unsaid! Why cant you women just say it and be straight forward like men!
