I enjoyed this and learned some things. I loved a lot of the linguistics facts. The history of certain terms was fascinating, as were the explanations of "girl talk" - things like gossip, hedging, tag questions, up talk, etc.
I have one major pet peeve though - I listened to the audiobook and was pretty annoyed at the way the author pronounced "Ojibwe" - “OH-jeeb-wah” instead of "oh-JIB-way." If you're going to use a language as an example multiple times, at least take the time to pronounce the language correctly!
