Mary Poppins was a nanny who had a huge bag that held almost everything she had. She had magic but not normal magic. She could talk to animals, go to wherever she wanted, and she could also fly away holding her umbrella. But she was very strict on the kids. She almost never got happy and never laughed. I would feel super happy if I had an extraordinary nanny like her. I really recommend this book to readers who like to be serious but also have a lot of sense of humor.
