Have you ever had one of those days? You know the kind: when everything just makes you want to scream NO! and those pesky dogs are always under foot? The kind when dropping your fork makes you hostile towards the world at large? Yeah, you know the kind. The kind where, when all is said and done, all you want is to do is get your favorite sun hat, snuggle down with a book called "Do you have a hat?" and answer YES! I HAVE A HAT! every time it asks. If you've never tried this book on one of those days, you should. It makes the world right again.
