Question the Chestnuts. Chestnuts: the new name for boobs? No. NO. Why would you even say that? Get your mind out of the gutter. No, by "chestnuts" I mean, "those old pieces of writing advice that you hear as common refrain." 'Write what you know.' 'Adverbs give Baby Jesus hemorrhoids.' 'If you write a prologue, an orphan loses his sight.' All the "old saws" need to be put on the chopping block.
