one's companions

She stood up like a penis,
unfolding herself lazily 
languidly and as if unawares,
stretched herself. Shook 
just a bit. Yawned, an effort.
Spanked herself on the fundament
once, totally unselfconscious
(one never really knows 
about such things) as if
to get herself in gear,
pretend-riled up, and left 
like the hole she left. 
Like the cup and plate
of crumbs she left. And I,
who all the time she was there 
had noticed she was there,
random along with several 
random others, had not noticed
who she was, there. Or why,
and will never know now. 
How could I?
