There is
a pane
of glass,
standing upright
and surrounded
by several different people.

A large hammer
is swinging
repeatedly
into the glass,
cracking it
more
and
more
over time.

Eventually,
the glass
s

    a
          t
  t    e
           r
      s
        ,
and the pieces fly
and hit the surrounding people,
causing wounds big and small.

The people stumble
and cry
and they wonder why
they could not see the cracks in the glass.
They wonder
if they could have stopped it
sooner.

But it's too late now,
and now they all bleed,
and now they all cry,
and some of them may die -

Because no one saw
the cracks in the glass.
