Magic Lamp: Josephine Believes She's Supposed to Be a Genie

Genie sighed, then said "I wish you'd forget about being Joseph and think that you're a real genie. It would make things so much easier." Josephine blinked, then looked quizzically at Genie. "But, Mistress. I AM a real genie. And who is this Joseph you speak of? Is he our new master?" Genie's eyes went wide. Her wish! It came true! And now Josephine ... she really thought that she was a genie. And she forgot everything about being Joseph Dell. Should Genie try to reverse what she just did, or keep things as they are?
