line in the sand

there's line
in the sand that you've
drawn
for many things.
unable to take it anymore.
to listen
or enable
those who behave
in bad ways,
and have their entire lives.
you finally break
and give it to them.
tell them exactly how you
feel.
this shocks them,
makes them defensive
and angry, but
never once do
they say,
maybe he's right, maybe
I should look in
the mirror and try
for once
not to be this way.
