It Sits

It sits upon the paving stone
or hovers on the wall
it moves like shattered lightening
or doesn't move at all
it trails a toe in runing stream
languid and at ease
or maybe tense and nervous
whatever as it please
no hand to hold
or outrage bold
or flittering anger brewing
no emotion cold
no story told
no mystery renewing
A plot too thick
perhaps a trick
a spider web in which to stick
or lose the time in thinking
but be at peace
we know at least
it may be ours
but is not beast
or sentinel bestowing this
or dweller heaving sigh
and guardian knows not whence it came
and tower knoweth not a name
yet it's sitting on the paving stone
and hovering by the wall
sometimes it moves like lightening
and sometimes not at all.
