basically i have done some research on this.........and the
conclusion i come up with is this.
girls, when they are young, have the tendency to chase guys that's
because they either got the confidence(always got guys chase them,
etc...) or they find the guy very perfect, far more superior than
the friends around her. when they get older or life settling
down(going out to work, etc....), they'll be more and more
reserved.
most guys of course will do the chasing especially older guys due
to the experiences and confidence they had as they age. girls no
matter how are passive creatures.
