Something to consider. I notice that BB likes to have his hand right near his mouth when he talks. I recognize that as a sign of deception. The mouth guard is one of the few adult gestures that is as obvious as a child's. The hand covers the mouth and the thumb is pressed against the cheek as the brain sub-consciously instructs it to try and suppress the deceitful words that are being said. Sometimes this gesture may only be several fingers over the mouth or even a closed fist, but its meaning remains the same.
Many people try to disguise the mouth guard gesture by giving a fake cough.If the person who is speaking uses this gesture, it indicates that he is telling a lie. If, however, he covers his mouth while you are speaking, it indicates that he feels you are lying!
