Bottle blue

Why do flies
choose to die
on the window sill..? 
like road kill
when the could
easily  fly
to the fluffy side
of the sofa.. 
it's the last
ditch attempt
to get outside
where they were
hell bent on intent
to get inside
and do the
square dance
lament around
the light..
What if there were
no sills..
or central bulb
to rotate their
single cell pilot skill?
it would be anarchy
of the insect world
