I'm not sure what I thought I was getting into with this book, but I found it to be rather dry and full of repetitive anecdotes. It also made a reference to evolutionary psychology at the end and made several references to Steven Pinker's work.
I'll admit that the book and I didn't get off to a very good start because I found it questionable the way it included racist-based swearing as a category in the list of basic types of swear words because it implied that the strong emotional responses to those words only validates their use as swear words (that's what I got out of her meandering arguments, anyway). It also highlights how swearing can help build team cohesiveness in the workplace while glossing over just how abusive it can make workplaces for those who don't play along.
I probably wouldn't have bothered finishing it except that I had finished my latest ebook, hadn't chosen another one, and all my other books on the go from the library were quite thick and harder to carry around.
