Body Language

Are people so busy talking that they have no clue that no one is listening? A few times this week I have seen someone perform a soliloquy to a bunch of people that had no interest in the conversation. The person droned on and on and never stopped to read the body language of those who she was talking at. That's right, talking at, not talking to.  Most conversations are just two independent monologues. I have learned that when I see someone's eyes roll back in their head and drool runs down their chin that the conversation needs to come to an end.
