You have walked past me and looked at me and smiled, and you have walked past me and other times you barely noticed me as anything other than an object. Truly, it is remarkable how little regard you, or any human, gives to something that remains completely motionless. You have woken in the night, got up, walked to the little toilet, micturated, walked back to your bed, slept once more, peacefully. You would not notice something perfectly still, would you? Something in the shadows?
