What Are You So Grumpy About? Is about this little boy who is mad about something, and it gives all the reasons you can be mad, while making it funny and entertaining. These books remind me alot of the No David books, which I'll talk about later. This book made me crack up when I was little and I give it 5 out of five stars, esspecially for good illustrations too. It now also reminds me of my angery little brother, but if I could get him this book I would. I think it has suggestions for cooling down.
