Like a giant shield
it guards private minutes
with the zeal of a shining knight
and the unmoving stare of a statue.
If you have a door, that is.
You hardly pay any mind to
the steadfast open/close
and take for granted the solid plank of wood
Jim Morrison managed to immortalize.
A five-lettered noun of dissonant reassurance,
that begins and ends at the sound of a click
or bang, if you ask for it.
