Where was his knife, upon which he relied? He had cut cheese for their noonday meal, and had packed the knife away with the cheese.Aillas said: 'Sir, before we continue with this matter, may I offer you a bite of cheese?''I care for no cheese, though it is an amusing concept.''In that case, allow me a moment while I cut a morsel or two for myself, as I hunger.''I have no time to spare while you eat cheese; prepare instead for death.
