Gloria is thrilled when she goes to the store to buy an onion and meets Dr. Grace Street, an astronaut. Dr. Street tells Gloria to have confidence in herself and that big problemsaren't always as big as they seem. Gloria hopes Dr. Street is right, but right now her problem seems gigantic. It's the beginning of fourth grade, and Gloria can't do anything to please her teacher, Mrs. Yardley, who roars and hisses like the Dragon of Doom. When Gloria writes a report about meeting Dr. Street, Mrs. Yardley doesn't even believe her. How can Gloria prove she's telling the truth?
