The style of the lettering and the background images are perfect for illustrating a foul mood. Written in a manner suggesting that they were drawn with a wide paintbrush, the letters give the appearance of having been spoken by a very unhappy person. The figures of living creatures are drawn in a minimalist style that appears primitive; some of them reminded me of what you see in ancient cave drawings. The point of the story is that when you are overcome with dark feelings the best thing to do is to ride them out, let things pass until the grumpiness goes away. There are only 57 words in this book, yet in combination with the illustrations manage to tell a complete and valuable story about living with your bad moods. This is a good book for young children.
