What's in a Voice?

That it is so much more likely to reveal the inner selve than any other feature?

Maybe sometimes it would just be sufficient to close your eyes and simply listen.

A woman, whom I knew to be pretty tough on herself and others, once had singled me out and was already attacking me verbally. Then I opened my mouth and she apologised immediately. I hadn't even addressed her verbal attack.

Like the wrinkles in one's face maybe one's voice remembers and reminds.
