Reading Body Language
When you look at a woman, here is what you do. Lock eye contact with her. Don't blink. Don't look at her friend. Pick one eye and don't let go. You only get one chance at this. Don't give up. Don't smile. Don't say anything. You are telling her that you are interested in her and you are not intimidated by her. Then leave it up to her. You will be amazed at the staring capability that women posses.
She is thinking "Who is this guy to be so bold as to continue looking at me while I look at him? Now this is interesting. He is different." She knows that if she lets go now, she will loose you. She will go one of two ways. If she wants to loose you, she will break eye contact and look away. If she does not want to loose you, but is instead intrigued by what you are doing, she knows that she has to eventually end the stare down and she will have to make the move. She will have to either smile or say Hi.
If she smiles, you smile. If she says Hi, you say Hi. Don't say Hello. Then you reward her and make your move.
Of course, you don't always have to wait for eye contact to make your move.
David Shade, ASF: "When you are talking to a woman, always maintain eye contact. This demonstrates confidence and intent. Don't theorize about it, just do it. Pick one eye and stick with it. Don't go from eye to eye, that is nervous. That can only be done with great skill as she will associate eye changes to content.
The only time you do not look a woman in the eyes is when you are "motioning away" as you mention something "bad", such as her bore-friend. Anything "bad" is associated with "looking away."
That is after you have already started talking to her. But what about before that? Again — always remain in eye contact. Let her be the first to break eye contact. Then make your approach. It does not matter what the setting is. It is universal."
