You're the type of person who understands other people and the world very well. You don't let on to how much you know.
You can tell so much from someone's facial expressions or tone of voice. And you always know when you're being lied to.
You show the world exactly what you want to show. Besides being good at reading people, you also know how you're being read.
You know when you're being manipulated, and you know how to manipulate
someone if you have to. You usually don't resort to it though!
