For my part, I never uttered the phrase concerned so all my life, and I never heard anyone else around me and say, so I left that puzzled (I can not quote because profanity are not acceptable in the comments, even when it comes to comment on a profanity of a book that speaks only of this). But my faith, I do not have the monopoly of the language so if you, dear reader comments, you utter this phrase as the book written, ignore my comment. Perhaps it is also a typo, but there has so few words in this book, it would tend to prove that it was sloppy.
