gray as air

Grey men are invisible. They sink their head into their shoulders, and disappear in to their elastic generous neck skin. Like vultures when they pull their head into the feathers. I bet that the vulture too thinks he is invisible as he looms up ahead circling, low key, flying high enough, he believes he is camouflaging behind the  flies, which are close to the ground .
Any way these grey haired men, hide in their hair, in their bad eye sight, and like little children believe that if they do not see you, you will not see them.
They pantomime next to grey stone walls and believe in their supernatural ability to assimilate with the wall. My father does it. He really thinks I don't see him as we by pass in the street, when he wears his invisibility cloak. As he is hiding behind obstacles in his own head. Or wearing red stands next to tomatoes in the market. That is until on visible days he passes me and says hello, what have you been up to?
 But its not just him. There are others too. The white haired photographer who turns into his hat when he wants to by pass a particular someone in a busy coffee shop. The man is incredible. He has white hair, white beard, wears a white hat, and his face just adopts the colour of some greenish white slimy mushroom, once he nears the unwanted potential hello. Of course people avoid him in that state. Than , as he escapes danger, his face turns back to glowing orange, his visible colour which welcomes greeters and accidental bumps on the street.
But its only the grey haired men, who do this, and really seem to believe , that the mind will over rule physics. They are not visible to the mortal eye. Its something about the hair. Grey as air. I'm as gray as air. Im as gray as air.....
