Well... girls love attention... so, you can just start any topic, pay all the attention you can, comment, make jokes, listen, and mainly be really interested in her. Try to ask her opinions, feelings, use this oportunity to know her better. With moderation, of course, for dont seem annoying. If everything goes ok, you will not even realize the time passing, and will wish the canyon were much further...
But, above of all, keep your mind cool. If she feels youre at ease, much probably she will become too. Relax, and go with the flow. Its the better way.
And good luck! :thumbsup:

PS. Does she smoke? If yes, its a very bonding thing to do and to talk about. :jointsmile:
