Mystery discusses the attraction signals girls send when they are in the vicinity of a man they wish would approach them.
He makes a very good point toward the end of the video. In groups of two or more girls who are loitering near you, it’s the girl with her back to you who is the one who finds you attractive. In my experience, this is true almost all the time. It must be something subconscious which triggers a clutch of chicks to automatically arrange themselves in this manner. The advantage it offers the interested girl would be a chance to discuss with her friends — who have their eyes on you and are judging your reaction to their presence — whether you are checking her out and how alpha you are up close, while simultaneously giving her plausible deniability that she would like you to approach.
See, girls have game, too. It’s called coyness.
