Three Ministers. Sally knew Percy had been older, but three Ministers put him squarely in the war era of the Ministry. If anything, it made her appreciate Percy a bit more, that he'd be willing to stay for his career (if nothing else). Ambitious men who weren't noble about it were rare indeed.
She laughed, "Oh, goodness, where to start. Animals are the worst, of course. I think first year Transfiguration gave many people the idea that turning animals was easy. Teacups into mice, what were they thinking? There was a man who wanted to give his daughter a krup, so he thought he'd transfigure some simple bed pillows into a beloved krup for his daughter. It did not go according to plan; the krup exploded on the little girl at one point, and her uncontrolled magic tried to put fluffy back together again, which resulted in the father being stuck in the middle of a rather bloody blob. The scene was absolutely horrific and we had to modify their memories severely - I'd have liked to leave his so he could live with what he'd done, and what he'd caused his daughter to do, but protocol doesn't permit for us to be judge and jury like that. Protocol says to wipe his mind, we do it. I do think my partner tossed in a serious aversion to krups on the part of the little girl though, so she wouldn't request them again." She took a sip of wine and pondered her last thought.
"Memory is tricky like that. We haven't quite figured out how to modify it completely, and you never know what will come and trigger into remembering details of the event - though do you know how many times we tell people they must have had a bad dream, and no, their memory wasn't modified? Too many." It gave her a little shudder, just thinking about it. She was glad she didn't have to live as an obliviator.
