This lucky policeman gets to shake hands with the President of the United States.

So obviously when we think about nonverbal behavior, or body language -- but we call it nonverbals as social scientists -- it's language, so we think about communication.
When we think about communication, we think about interactions.
So what is your body language communicating to me? What's mine communicating to you?
And there's a lot of reason to believe that this is a valid way to look at this.

And we make sweeping judgments and inferences from body language.
