Don''''t ask her for it.
Yes, this doesn''''t sound right, does it ?
But the best way to get a
number (a REAL number) is to not ask but
rather structure an
opportunity for her to get with you, after you''''ve
already done the work of fascinating, attracting, and seducing her.
Once she is excited about you, she will fall over herself to give you
her number once you''''ve structured an opportunity for her.
You can do that with some NLP
negation (you: "Hm, I''''ve got to go. It''''s
been nice talking with you. It''''s too bad we won''''t be able to have an
interesting conversation like this again..." her: "Of course we can,
here''''s my number!") or you can do it by asking her a to
provide a
suggestion as to how you could hook up again (you: "It''''s been nice
talking with you. Can you think of a way we can get together and do
this another time?" her: "Sure, here''''s my number!").
