I told that to my mother, who edits textbooks (she's actually editing a biology AND a psychology textbook right now. She says that since she started in the business, not a single new thing has been in the psychology textbooks, none of them), and she was horrified. Legitimately horrified.
Edit: as for the "apron" bit, I don't understand. I spell it "apron". I don't think I've ever seen alternative spellings...
