Husband: “Dear wife! Education is easy and it is difficult. In the present case I would advise you not to tell the children “If you love uncleanliness, that’s how cholera comes,” but rather just to say: “If you are clean, then cholera doesn’t come!” That would suffice everywhere for a bit of sense, and fear and terror would be over.”
(Nebelspalter, Zurich, 1883)
