1) IF you are handsome, no need to talk cos gals will fly to
you.
2) If you are rich, use money to buy her things, no point
talking.
3) If you are able to sweet talk her, you will not complain
here.
4) If you have no skill as above, try this
target her friends instead of her talk to her friends,
cos is a proved fact that you will be less shy if you do not like
the girl.
The plan is to talk to her friends in a group and she will start
chatting with the group, talk normally and when the group starts to
go away, ask her to talk more with you alone.
