The reality of working at the Ministry was much different than the fantastical, naïve dreams of her youth. Actually making any significant change was virtually impossible unless one was willing to slog through the muck and mire of a political bureaucracy. It wasn't a glamorous life by any stretch of the imagination. She was forced to make deals and alliances with people she wouldn't spit on if they were on fire. All done, of course, with a bright smile. If she'd known what the Ministry was actually like, she would've done something more worthwhile. Like study dragons in Romania like Charlie Weasley. At least with those creatures one knew to expect fire and danger. Her Ministry coworkers were just as deadly, but a great deal sneakier.
