Sprayed by Fish Scales

Window cleaners beware!
There be fish scales here,
obscuring the lovely view.

Looking sometimes like snow, and
sometimes like hail,
there are some nasty spots to block
the clear vision of water and landscape.

Hidden beneath the view, there may be
sea monsters! or other nasties come
to ruin the day of landlubbers like
us.

Best thing would be to clean the lenses
through which we are viewing
the living environment around us!
