i guess that's it

I am awakened in the middle
of the night
by the neighbors making love.
pedestrian love.
the picture on my wall
shimmies on the nail, just
slightly, but
it startles me,
having never heard a word,
a single word
from either of them
the entire time
they've lived there.
no television, no music,
nothing but silence.
and now this,
the symphony of bedsprings
and the steady
rap of a headboard
against our shared wall.
thirty seconds later. it's over.
the dog sits up and looks
in that direction,
turning his head, as dogs
are prone to do, then looks
at me.
it's okay, I tell him,
I guess that's it.
go back to sleep.
