[durham_rambler]

"The practice of hinting by single letters those expletives with which profane and violent people are wont to garnish their discourse, strikes me as a proceeding which, however well meant, is weak and futile. I cannot tell what good it does - what feeling it spares - what horror it conceals."

Charlotte Brontë in the preface to a new edition of Wuthering Heights.
