Well, it's a timely investigation for sure. It turns out that JWoww's guide to life and love, "The Rules According to JWoww," came out the same week as "The Jane Austen Handbook." Slate did a great side-by-side comparison.
While the Ms. Austen guide had a distinct lack of GTL, it turns out, it's not for the timid or the proper-er-than-thou. An excerpt:
Ask him if he wants to go "stargazing." Everyone knows what that means. If not he must be rather clueless, and perhaps you should rethink your affection.
Excellent advice for shore-dwellers and land-dwellers alike.
