This book shows real insight into human emotion and interpersonal dynamics, presented in a very gentle, simple way. Why he gave up and became the gender stereotyper from hell, I don't know. I guess because it sold better. Too bad, because this is the better approach. He discusses the dynamics of emotional connection without resorting to "men do this, women do that" by showing that when one partner, regardless of gender, behaves a certain way, the other will respond accordingly.
The tone of this book, again, is simple, almost childish, but gets the points across. "The Two Step", is the grown-up version.
