"It would be such fun to have a girl playmate of my own age, you see. And Hank is such a dear little mule!" Ozma laughed at the wistful expression in the girl's eyes, and then she drew Dorothy to her and kissed her. "Am I not your friend and playmate?" she asked. Dorothy flushed. "You know how dearly I love you, Ozma!" she cried. "But you're so busy ruling all this Land of Oz that we can't always be together." "I know, dear. My first duty is to my subjects, and I think it would be a delight to us all to have Betsy with us."
