Men who are dating the first time may ignore subtle signs from girls who like them. An old joke says, "It is easier to learn rocket science than to understand a woman's thinking!" Some women play hard to get to see how much effort you are willing to commit to having them in your life. Many men face the dilemma of either chasing their dream women or let them go. When dating, men are expected to understand the vital signs of girls who want to be pursued.
