Talk about the new restaurant nearby, that you both need to visit soon..
Talk about her favorite book, author or magazine.
Ask if she likes sports. If yes, which?
Find out what is her ultimate fantasy.
Ask her what her childhood was like, and what her family is like.
Pet peeves and fears - talk about them. Let the girl describe them in full detail.
Ask if she believes in the paranormal.
Ask if she has been in love before.
Know what's her take on love.
Find out what makes a perfect guy for her.
Ask if she likes to party. If yes, how much does she party?
Talk about the things (habits) she detests most in people.
So, you see, there is just so much. I have merely scraped the tip of the iceberg here. Go on and plunge into the depths of how to talk to people. Try it out. Girls are sensitive, if girls know that you are making an effort, they will appreciate it. Most of the girls find it cute as well. So, don't worry, it ain't an exam to pass, just something that a guy has to do, right?
