Eye Patterns (NLP)
Eye Accessing Cues is fun stuff, part of the huge NLP toolbox. With knowledge of this, you can tell what a person is doing inside their head (including lying), and create more rapport using their sense preferences. I bring out this trick whenever, once I talked to a girl who literally tilted her head up and to her left to VR. "Oh I remember when..." and then totally shifted her head down and to her right to K "and that made me feel sooo..." hehe.
