find out what she's interested in, and ask her about it. at the same time thou, talk about what interests you. basic human nature is that we like talking about ourselves, a lot. let her do that, but make sure that you add your own input as well.
Ask her just about anything, and if she finds you interesting she will make the conversation flow no matter what. Ask her about favorite movies, hobbies, favorite subjects, family members. You name it.
ask her what she likes to do in her freetime, what her hobbies are, what type of music she likes, ummm what type of movies she likes, and if she likes sports- if so, which ones? f you have anything in common with her, maybe ask her to go to a concert? movie? sports game? what she looks for in a guy. hope this helped! :)
Just be funny and joke around with her. Just like megcarr22 said...ask her about herself, her family, hobbies, about her weekend, how she's feeling, about her childhood, anything, and once she starts talking, things will come up and it will come natural after that.
Best way to a woman's heart is actually crack a joke not really prank jokes but just be funny most girls love funny men and when girl seems to laugh at you she will actually starts asking other questions or starts the conversation..
