This is a great little book for both young readers and old. It was a gift to my daughter from her Aunt. Even thought my little one is only 2 1/2 years old she can relate to a story about cookies, she identifies with the page on being PATIENT it means "...waiting and waiting for the cookies to be done..." if I ask her to be patient she reminds me "like the cookies" I am identifying with the meaning of Pessimistic VS Optimistic. Pessimistic means "How awful, how absolutely dreadful-I have only half my cookie left." VS Optimistic means "This is great- I still have half my cookie left."
