"Once upon a time there was a squirrel called Fifi. She had a friend called Leo who was a marshmallow..."

"Can you please, please, let me study in peace?!" cried the bushy haired prefect, banging her book down on the table.

Harry looked up from his book and gazed at her incredulously.

"I haven't done anything!" he protested.

"Harry!" said Hermione sternly.

"Fine, I'll let you study in peace." snapped Harry, "Even though it's not like I did anything in the first place..." he muttered, going back to his book.

Hermione glared at him, picked up her quill, and started working again.

"One day, Leo and Fifi decided to cross the forest to visit their friend, Norbert the Bear..."

"Harry!" exclaimed Hermione crossly.

"What!" replied the raven haired boy in the same tone.

"Stop. Disturbing. Me." hissed the girl angrily.

"I'm not. Disturbing. You." Harry hissed right back at her, "I'm just reading."

The bushy haired girl huffed.

"Do you have to read that crappy story out loud? Rather, do you even have to read it at all?"

"Crappy?!" Harry cried dramatically, "Crappy?! I'll have you know that Fifi the squirrel is awesome, she's even better than Rupert Bear!"

"Well Rupert Bear is hardly a reference..." muttered Hermione.

"What do you mean, hardly a reference?" protested Harry, "It's one of the greatest books of all time!"

"Whatever..." Hermione sighed.

"Anyway, Fifi the Squirrel is a must-read! The way she braves the dangers of the forest to see her friend is really amazing!"

"Heroic." Hermione added with a hint of sarcasm.

"Right?" Harry continued, oblivious to his friend's lack of interest, "And Leo the Marshmallow is such an interesting character!"

Hermione sighed and started looking around for an escape route.

"Oh, Harry!" she exclaimed, slapping her forehead, "I just remembered I need to talk with Professor McGonagall!"

The girl hastily left the common room. Harry waved at her retreating back with an angelic smile. Once Hermione had disappeared through the portrait hole, he glanced around with an evil grin. He quickly spotted his new victim.

"Hey Ron!" he called to the read-haired boy playing with his chess board on a sofa, "Mind if I sit with you?"

Moral: Children's stories can hide a lot of evilness.
