I didn't read the whole thing, but it has some really interesting ideas about how the language we use affects the relationships we have. I of course was concerned mostly with how I talk to my students, but I think this book has a lot of useful thoughts on just general conversational skills. Like how often we react with judgment when someone we care about is upset, instead of just listening and empathizing with them. It sounds very floofy when I describe it like that, but whatever - I liked it.
