It’s just like a casual date where your job is to break the ice and give her all your attention. A good start to break the ice is to talk about neutral subjects, like the weather, the song of the week, compliments on her dress, hair, purse,etc. If she is shy, then you will carry on the conversation, but give her some space. If she is expressive then eye contact is very important, if she is just listening attentively and does only subtle movements to compose herself, then she is probably an analytical type, she would be interested in the details of your story; a turn-off to her don’t look over the side when another attractive lady passes by. Have a good repertoire of good stories and jokes. She wants to know if you are non threatening and easy to get along with. Beware not to show you are nervous by constantly fixing your glasses, your hair, your watch, etc. You guys should take care of the bill.
