under the grey rock

she hides the key
to the house
under a grey rock.
it's to the left of the porch
she says
in her message.
there are a hundred
grey rocks
though.
I turn each one over.
one by one
searching for
the key.
there are other keys.
I try them in the lock.
they don't turn.
I keep looking.
rock after rock.
soon it's dark
and there's one last
rock.
it's there.
I find it.
