Toothbrush?

[alt_myrtle]

I was just laying in my pipe when I heard the door close and then I heard crying. I came up out of the pipe and peeked through the stall door and saw Hermione crying. Then she took a toothbrush out of her pocket and started to scrub the toilets. What's going on? And what a silly thing to use to clean the toilet.

And I hope she doesn't use it to clean her teeth afterwards.
