What Shamu Taught Me About Life, Love, and Marriage by Amy Sutherland

Based on an article that originally appeared in the NY Times in 2006 (link here), this is a fascinating look at how we can train other people (and how they can train us) to do things we don't even realize... and how to *avoid* accidentally training someone to do something you don't want to happen. It's hard to put down this book, and I'll definitely keep it close by so I can read through it and refresh my memory when I'm having trouble dealing with a difficult person.
