I like to think that another aspect of our personal Echo is that it subconsiously encourages people to trust us and tell us their life stories... and more importantly be inclined to take us at our word and entrust us with important tasks or information, or believe us when we are telling the truth but the evidence isn't all that convincing.

It explains a lot of the wonkier bits of storytelling, if nothing else.

Also, gives us the ability to communicate with others despite not actually speaking 90% of the time
