the nun

the nun
with her ruler
and black
shroud
rimmed in white
haunts you,
every mistep
along the way,
every left turn
you've taken
when you should
have gone right.
she's standing
at the front of
the room,.
slapping a ruler
against her
pink hard hand.
her black eyes
shadowed
by the cross
and the altar,
the centuries
of evil disguised
as good.
