How do I act like a 27 year old woman?

My class is making a play, and my character is a 27 year old woman who has recently started internet dating and fancies a 29 year old man she met online. I need to know how a 27 year old woman should act with a 29 year old man. How can she flirt with him so he becomes interested in her? What questions can she ask that would help her to get to know him more? Does she always need to have a formal tone with him? Any additional tips are welcome.
