Obliviation was a difficult bit of magic to master; all mind magic was. If only Dumbledore had bothered to explain that before throwing Harry at Snape for Occlumency lessons. Kingsley took the time to explain to Harry. The Minister had almost become an Oblivator instead of an Auror. He joked that would have made him a better politician, people would forget his mistakes. Kingsley said the most important thing was compartmentalizing your thoughts. Harry had joked with Hermione how she would be a good Oblivator. He only did it once. She had broken down crying and told him about what she had done to her parents. He felt awful. The worst part was that she couldn’t reverse the memory charms. She had been devastated when she returned from Australia without her mum and dad.
