I picked this up at the library, it's one of those fluffy books you know you'll enjoy without much effort. What made it really enjoyable was a post-it note stuck to the index page which listed in short the 100 reasons why dogs make you happy. The post-it note added two more reasons. How thoughtful of that reader. Now I feel like I have to keep this chain going and add reasons of my own. It shouldn't be too difficult. I have expert help at my ankles.
