She didn't know who thought that this would be a good idea. They were a bunch of Muggle children, singing some inane song at the top of their voices, sounding as insane as she did on a normal day.

And she was going to have to spend the entire day with them: the Ministry's attempt to show her that the Muggles weren't as bad as she thought they were. No, they were much worse.

Bellatrix was supposed to be in charge of a bunch of the brats for the day. She already knew that this was going to be more than a little amusing. The day would probably end with her having a headache and itching for her wand to curse the brats into oblivion.

Not that she was allowed to, nor would she even get her wand back until tomorrow. 'Just in case' she reverted to her psychopathic tendencies, or so they had told her that morning.

Ridiculous.

"The wheels on the bus go round and round…"

Bellatrix cringed. Did they have to sing about something so pointless? They weren't going to move if the wheels weren't bloody going round and round. She certainly didn't hope that this trip continued all day long.

Turning at the feeling of her sleeve being tugged on, she laid eyes on the smallest girl in the group with the loudest voice, and two innocent-looking ponytails that Bellatrix just wanted to cut off her head.

"I need to pee," she said in a stage whisper. The busload of brats had chosen that moment to go startlingly silent before breaking out into laughter.

Bellatrix did not want to deal with this.

Where was their bloody teacher? Right, the man was asleep, completely ignoring the madness of the children around him in favour of catching up on his sleep! Bellatrix didn't think the man even knew of his recently added moustache or eyebrows. He would find out soon enough, but there was a reason she had never had brats of her own: she had considered it, but the cons far outweighed the pro.

The silence returned slowly as they waited for her answer. Bellatrix got the feeling that this had been well planned and probably happened to ever new 'teacher' that had the misfortune of being welcomed into their class.

Bunch of brats.

"Language such as that should be kept to oneself," Bellatrix replied, voice in an equally loud stage whisper. The girl looked confused for a moment.

"Oneself?" the girl questioned. Bellatrix nodded and leaned back. Their dear teacher was going to be absolutely delighted when they all start using 'oneself' for no reason. She had heard that the man took a great delight in correcting his peers' spoken language.

Perhaps Bellatrix would join them, using the word correctly, of course.

There was no reason to deny herself a part in the man's nightmare.

She couldn't wait to hear the screams.
