A younger brother has little choice but to look up to his older sister. She is taller than he is, for one thing. She has many developing talents, ranging from karate to violin. And she knows so many things: How to make the living room into an adventure land. How to dance. How to grow gumdrops. Well, maybe her understanding of the world isn't perfect, but she's pretty impressive, leading Little Brother to call her "Me one" and himself "Me, too". Big Sister also loves to share her knowledge, particularly with her best friend, Kittywumpus, the family cat. However, after a possibly too vigorous "makeover", Kittywumpus runs away for a much-needed break, leaving Little Brother as the new target for Big Sister's ministrations. And while it's fun at first, the dressing up and the tea parties and the cream cheese on the piano start to make Little Brother think that the cat might have had the right idea. But then, an impromptu performance in his sister's tap dancing class earns kudos for both siblings, giving them each a new respect for each other that continues even after Kittywumpus returns.
