I read a study that said that something like 90%, the vast majority of male-female interactions between potential mates are instigated by women. Although non-verbally. You see, guys have the inner fear of approaching. So girls will give signs to a guy to signal their "openness" to being approached. This may be a glance, facing you, or most obviously a smile. It's there way of saying "I find you attractive, talk to me". Now my question is. 1, how does a guy who's never been in the scene learn what these signs are? or better sense them? and 2 how do you become the person that, without even talking builds enough attraction to not immediately be crossed off from a woman's list of "potential mates".
