"I know what you're thinking."
Ever have anyone do that to you? Splash right into the big puddle of your thoughts and you suddenly feel exposed.
Then you relax. Of course they can't read your mind. They can only guess.
Or they can gently ask, "Penny for your thoughts."
(Why is it always a penny? Our thoughts are valuable. Should be a million bucks for your thoughts.)
What's interesting is how we respond. I think we tend to dodge and weave.
We don't reveal what we are thinking. We shrug it off with, "Oh, nothing important."
