There was nothing you could do but pack up the dog and leave.
Was there nothing? You could do nothing. Could you leave?
Nothing could leave you, but you could leave. Could
you pack up nothing? Could the dog leave there?
Could you? Do you? Nothing there. Pack and
do leave. The dog could leave you there
but pack you up. You do, do you? Do
pack up the dog and leave nothing
up there, could you? Nothing but
the dog. You? There was the
dog, but there was you
and nothing. Pack up.
Leave the dog.
