The Neurological Component of Silence

So one of the things like I've been watching my audience as I watch individuals all the time because I'm always talking to individuals in an audience it's a good thing to know if you're a public speaker by the way is you only we're afraid to talk to a group if you talk to the group well you should never talk to the Group. You can pick people out in the audience one by one and you can talk to them and then you can see if they're following or not. If that person is following then probably almost everyone else isn't. So anyway so well the other thing I do is listen to the the whole theater and I'm always very curious about listening for silence
