This body had experience writing self-critique papers, and the experiences Flossie Wright had now were all accumulated previously.
She was never associated with the adjective "obedient" since childhood. Plus, starting martial arts at three and having skills without an outlet only left her to bully her peers. If she bullied too hard, she had to write self-criticism at school or home, even dozens at once.
She was a typical naughty child, naturally disobedient. Self-criticism was a little difficult initially, but with practice, she was able to write dozens in a night. Sometimes, when idle, she'd write in advance, saving them for when she messed up.
Of course, she stopped all this as she grew up. Even if she were to poke a hole in the sky, no one would make her write self-critiques. Fortunately, her experience came in handy to deal with several critiques within the Forces.
No matter what causes mistakes, what leaders want to see is just the same combination.
