Disclaimer: Yeah, right. I wish I was JK Rowling. Don't own anyone but Minerva Stewart.

A/N: Just a precaution. The OC in this story, Minerva. Is just that, an OC. Not Minerva Mcgonagall. Sorry if I confused you.

In the middle of the night, two girls snuck into the Gryffindor boys dormitory. Sweeping their eyes over the entire room, they finally spotted their sleeping prey. They silently crept over to his bed. Stifling their laughter, one of the girls took out their wand. There was a flash of bright light and the girls quietly made their way back to their own dormitory.

"WHO DID THIS!"

I woke up to the glorious screech of Sirius Black, which could be heard from where I was sitting, and that was a long way off from the person who had uttered this most glorifying screech. Biting my lip to contain my laughter, I sat up, yawned and looked around curiously like I didn't know what had happened. I got up and got dressed and did everything I usually did before breakfast and hurried to get down to the Great Hall.

I'd figured that Sirius was one of those types of boys that wouldn't give up a meal for anything. So, I wasn't surprised to see him down there. I also wasn't surprised to see what had become of his hair. Well, technically, absolutely nothing had happened to his hair, except that it had been moved...from the scalp of one teenage boy to the floor of one very messy boys' dormitory. He sat there, sulking and glaring suspiciously at anyone that walked pass him and snickered.

Then, he spotted me. He immediately stood up, the light glinting off his shiny head like a new Galleon. I smiled.

"Hey, Minerva," he said as he put an arm around my shoulders. My name was said through clenched teeth. I could tell he was trying very hard to keep a smile on his face and not explode.

Of course he'd suspected me. We hadn't been the best of frie- okay, so we hated each other. The first time we met was when I, being oh so clumsy, fell down the stairs and broke the tiniest tip of a twig of his precious new broomstick. Boohoo. We'd been arguing from then on.

"Hey, Sirius," I said nonchalantly. Can't give anything away, now can we?

"Yes, I was just wondering if I could speak to you, outside?"

"Oh? But what could you possibly have to say to me that you couldn't say in front of the whole school?" I asked in my wouldn't-hurt-a-fly-ever-so-innocent voice.

"You'd be surprised." He was still talking through clenched teeth, and I was still trying to keep from bursting into hysterical laughter every time I took a peek at his shiny scalp. He grabbed my upper arm and practically dragged me out of the Great Hall.

Once we found a vacant classroom, we walked in and shut the door behind us. I was smiling as if there was nothing wrong and Sirius was grumbling. I caught the words 'baldness' and 'dirty rotten' more than a couple of times.

After some minutes' silence, Sirius spoke up, glaring at me through squinting eyes, "I know you did this to me."

"Did what?"

"DID WHAT? DID THIS!" he said, pointing to his head.

"What? I had the impression that you decided to become a Tibetan monk or something."

"Not funny. Do you know what'll happen to the female population of Hogwarts? They'll be devastated!"

"You are so conceited."

"I oughta hex you for this!"

I sighed. We'd had duels before and I honestly think that we're evenly matched because neither one of us ever managed to beat the other.

"I don't have time for this!" I looked at my watch(which was a gift from one of my mum's muggle relatives) and suddenly noticed that I was going to be late for Transfiguration.

"Are you scared I'm going to win this time?"

" No, look," I showed him my watch.

"What's that?"

Oh, right. He's pureblood.

"It tells time. And right now, it says that we should be in class. So, I got to go. Bye"

I walked out, slamming the door behind me.

No doubt Sirius went to Madam Pomfrey for this because the very next day, all his hair was back. He wouldn't speak to me for about a week, and I was perfectly fine with that. No arguing, no Sirius, no surprise pranks, no Sirius, no aggravation, no Sirius, no Sirius, no Sirius...
