When I arrived they apologised on behalf of the dog. Note to all future and potential clients: never ever apologise for the dogs (or whatever other creatures you keep.)

"What the dog perhaps hears" by Lisel Mueller is very appropriate (especially with the imagery of growing children.)

If an inaudible whistle
blown between our lips
can send him home to us,
then silence is perhaps
the sound of spiders breathing
and roots mining the earth;
it may be asparagus heaving,
headfirst, into the light
and the long brown sound
of cracked cups, when it happens.
We would like to ask the dog
if there is a continuous whirr
because the child in the house
keeps growing, if the snake
really stretches full length
without a click and the sun
breaks through clouds without
a decibel of effort,
whether in autumn, when the trees
dry up their wells, there isn’t a shudder
too high for us to hear.

What is it like up there
above the shut-off level
of our simple ears?
For us there was no birth cry,
the newborn bird is suddenly here,
the egg broken, the nest alive,
and we heard nothing when the world changed.
