I wouldn't necessarily try to change yourself to be more like anything else or anyone else. She is flirting with you because she likes YOU. She likes your style already.
So be you. If you're quiet and gentle, then be quiet and gentle, with a smile. Let her tell jokes, and laugh at them. If you try to out-joke her and out-wit her, that might not sit well with her.
Remember, she's flirting with you because she's fond of you the way you are.
