The wind settles and he's gone again.
Was he even there in the first place?
A trick of the light. Or maybe much more. A glimpse of the truth behind the veil. A brief and fleeting moment of utter reality, wherein he has no where to hide.
Wherein you realize—you should be the one hiding.
But where did he go?
Gone again with a gust of the wind.
Perhaps just a trick of the light.
