Be calm and stay cool,
take control of the situation to show her u can control any situation,
give her the impression that u always know what u r doing without showing off,just let it slip through naturally,
ask questions first,let her have the talk,
(what to hear/music, where to go/traveling,
what a beautifull dressing she wears,she is a woman with great taste,what she wonna do in her life etc etc)
this way u avoid to make a fatal mistake from the begining
and u learn more about her so u can adapt ur strategy,
(u must always show MONEY+MANNERS)
tell her what she wants to hear,
tell her u like her but dont let her understand she totaly onws u from the begining,
girls some times just wonna play with u, to proove themselves,
esp when they look too easy when they soudnt,
dont hesitate,make small but sure steps,
play with her,let her come to u,
find a way make her consume alcool,
even if she doesnt get drunk,it always have an effect,
get atleast two "protectors" with u
and put them in a dif wallet/pocket,
dont force,but dont forget it either,
be always ready to grab the chance,
avoid the embarassing moments
and take it easy,
good luck!
