The Presence and Tone speaks loudly

When Caitlin talked about being talked to a certain way makes us believe that someone knows what they are talking about, it made me think of how we talk to dogs, in that we can say anything in an excited voice, whether it is bad or not, and the dog gets excited.  I know my family would do this to my dog; we would say "bad dog" in an excited voice and he would get all riled up and excited himself.  Dogs do not understand us, but it is our presence and tone of voice that they respond to.  Now I am not by any means saying that we are like dogs, but if we do not pay attention to or understand what someone is saying, it is the presence or tone of voice that we respond to like thinking that Stephen Colbert is a serious reporter if we do not pay attention to what he is saying.  Here is a video of a dog responding to the tone of the owner's voice; at one point she says "bad boy" in a cute voice, but the dog does not respond until she says "bad boy" in an angry voice.
