Women, what are some cues that you want to be approached?

To be honest, if a woman is showing you resistance, she is NOT worth the effort. YOU should approach which ever women YOU want. Just be friendly and direct, no corny lines. If she smiles or does her part in carrying the conversation (don't expect half though) you might have something. Either way, whether she tells you to f off or jumps in your lap, it's no biggie either way
