Are they alive ?..... which one is ?..... as we watch them looking for a sign of life , a twitch in a muscle the blink of an eye , a slight smile , which one is alive. Watch them carefully what are they tying to communicate to us. I have seen the twinkle in the eye , the slight smile in return for ours , observe them with respect and it will be returned in kind . They spend there lives entertaining us and trying to communicate with us , are we listening. Listen and observe them in silence and we may learn what they have to say.
