This book, apparently, has unleashed a revolution. I've heard it referenced twice this week. Born from a Sex and the City episode, it turned into "The Rules" for the 2004 single woman. One friend described it as a "tough love" book for women - if he doesn't call, it's not because he's been working late, or is always busy or tired. He's just not that into you. If he doesn't make plans for the weekend by Wednesday, it's not because he's not a 'planner.' He's just not that into you.
I can imagine that there are men out there who think this is ridiculously simple, and are appalled that it took a book to communicate these things. To you men, I say - perhaps you were just getting too much credit all along.
