They have a lot of things they like to do. Gloria invents funny and thrilling games that would not be as exciting without her friend, and Robbie likes listening to her amusing stories for hours. Even when Gloria tells him well-known fairy tales, it makes him feel delighted and he wants to listen to her stories again and again. He even agrees to be "a big silver air-coaster" for Gloria when she promises to tell him the story of Cinderella again. They have become very close friends and seem to understand each other very well. Gloria enjoys Robbie's company and the robot seems to be a very caring nanny for the girl.
