There are some days you may wish you were a mind reader.

For example, in a job interview, you may wonder if you're making a good impression on the hiring manager or boring him silly. Or, perhaps you present the boss with your new idea, but you wonder if she thinks you're brilliant, or about as smart as a bag of rocks.

If you could just know what a hiring manager or a boss -- or even a customer or colleague -- were thinking, it would certainly save you a lot of stress and aggravation, couldn't it?

Nonverbal communication is everything that's not a word. It could be how quickly someone responds to a question, or how they tilt their head while listening to you.

If an interviewer gives you more time to answer questions, it means things are going well. If the hiring manager is cutting you off, it can mean that things are going downhill.
