If you approach a woman and hang around, she will look at you.
If she likes what she sees, she will look at you and smile.
If she avoids looking at you, she may be unsure or not interested.
Then you must smile at her with a foolish grin and say something corny, like "how can I tell if this melon is ripe?" or "can I buy you a drink or are you here with the best looking guy in the place?" LOL
RE: Ladies...?
