Christina's revenge:

Dear Professor Dumbledore,

I've written this letter regarding one of your students, Sirius Black, I'd like to complain about his behaviour. I find it very disturbing how he constantly interrupts in class ant hen looks at me with those beautiful grey eyes if to say: "Come get me..." It completely takes me out of my concentration.
And then all the pranks he pulls besides class, and afterwards you just know it was his work but then he smiles so sweet you can't turn him in. This is very bad for my health, every time he throws back his perfectly black hair or winks at someone my heart stops beating and my stomach turns 360 degrees.
It's just impossible to be around him and think straight at the same time. That's why I ask you to put him an a leash, a nice black collar with a chain attached. He's to hot to be walking loose. If you need anyone to hold the leash, I'm always available for walking him.
I hope you will take my advice
Sincerely Pr

Sirius looked up from the letter Dumbledore had handed him and smirked: "Well, I AM attractive..."

Dumbledore sighted: "This isn't all there is to know, I didn't get this letter by mail whatsoever, I found it in the typewriter..." He swallowed.

Sirius looked at him: "What professor?"

Dumbledore swallowed again and blurted out: "I-FOUND-IT-IN-THE-TEACHERS-LOUNGE."

Sirius gasped and clenched his stomach: "Professor... you d-don't mean thi-this is written by a Professor?"

Dumbledore nodded and asked Sirius who looked more then nauseated: "Do you have any idea who could have written it mr. Black?"

Sirius shook his head: "No idea, and I don't want to know who wrote it either to be honest."

Dumbledore nodded again: "Well then you can go, have a nice day mr. Black."

Sirius nodded back and turned to leave the room when the door opened and Dumbledore stepped in. Sirius' jaw dropped and he looked back and forth between the two Dumbledores: "What the f-"

"Would you please watch your language mr. Black." The Dumbledore at the door warned.

"Damn! You just couldn't have waited a couple more minutes." The Dumbledore behind the desk had slammed his fists on the desk and grinned to the Dumbledore at the door. He grinned back and said: "Well Christina, I knew you were going to revenge the whole 'Sirius turning your whole wardrobe pink' thing but why as me?"

Sirius gasped and started to walk furiously to the Dumbledore behind the desk who started changing into a fifteen year old girl who asked Dumbledore: "How'd you know it was me?"

Dumbledore grinned at her and said: "You're my granddaughter, I'm supposed to."

Sirius held still about 3 feet in front of Christina and pulled his wand, but she was quicker and had already stunned him before he could even open his mouth.

Meanwhile Dumbledore had walked to his desk and picked up the letter. When he'd finished reading it he asked his granddaughter: "I don't get how this is revenge though."

She smirked: "How 'bout if you include the fact that it's supposedly found in the teachers lounge?"

Dumbledore glared at her: "Sometimes I wonder why you aren't a Slytherin."

Sirius mumbled something areeing, which you could only hear by his tone because he was still stunned.

Christina bowed to both of them and then asked Sirius: "Do you promise not to kill or harm me in any way if I de-stun you?"

Sirius mumbled something that sounded agreeing again so he de-stunned him.

Sirius wanted to argue with her when Dumbledore interrupted: "Mr. Black, go to your dormitory, you'll get to argue later. First I have to talk to Ms. Black about other peoples offices and how you ask before you use them."

Christina grinned sheepishly and muttered a "Sorry" while Sirius walked to the door, before he closed it after him he glared daggers at her while saying: "I'll get my revenge, you'd better watch out." Then he closed the door.

Christina turned to an angry looking Dumbledore, he stood with his arms crossed in front of his chest and looked furious: "So ms. Black..."

She swallowed: "Did I already say I was sorry?..."

So? What do you think? Please review.
