And to Think That We Thought That We'd Never Be Friends — Mary Ann Hoberman

In rhyming verse that's a deliberate homage to Dr. Seuss, poet and picture book author Mary Ann Hoberman takes on quarreling and its consequences, and shows how turning fighters into friends leads to greater peace. It all starts with a fighting brother and sister, who make up with the help of another sibling. When the family begins fighting with their noisy neighbors, it's music that brings them together. Soon the whole town is marching in a parade, and eventually the parade swells to include the whole country, and even the animals. By the end of this optimistic picture book, the whole world is united in friendship.
