This just did not hold my interest - my mind was constantly wandering. The premise is interesting enough: that a person's use of small words that don't convey the content of a thought are more telling than you would think. They indicate who has the power in the conversation, and whether you'll react well to someone's speech, things like that. I found the book very dry and a little too repetitive, as the author discusses a variety of studies that essentially test the same concepts in different contexts, to see if they hold. Can't say I would recommend this, which is disappointing.
