------------------------------------------------------

Hogwarts School of Witchcraft and Wizardry, the most prestigious academy in the world, educator of the elite and of nobility - and an all boys school. This is also my new school. My name is Harriett Janice Potter, I'm fifteen and also the girl-who-lived. Ever since someone tried to steal the Philosophers Stone from Hogwarts, Albus Dumbledore, the headmaster of Hogwarts, has been trying to convince me to leave Beauxbatons and go to Hogwarts instead. This year he finally convinced me, which is why I'm going to be attending an all boys school. I'm also going to have to spend the whole school year pretending to be a boy. Yeah, it pretty much sucks but at least I'm not going to be at it alone. I made Dumbledore allow my two best friends come with me. So now Hogwarts will technically be an all boys and three girls school. But only Dumbledore, me and my friends know that. And we've all been sworn to secrecy.

"I never thought I'd actually be pleased at having an extremely small cup size." Lisa laughed, watching me and Hermione wrap our chests.

"Oh shut up Lisa," Hermione grumbled, "does it have to be this tight?" she asked me as I wrapped the bandages around her chest. "I can barely breathe in this thing, couldn't we just use magic?"

"I already asked," I told her, bringing the bandages around again, "Dumbledore said only if we could do the magic ourselves, since neither of us is even close to doing that kind of magic, we're stuck."

"What about polyjuice potion? I bet I could brew some."

"Do you really want to drink that stuff once an hour for the whole school year? Besides, the use of polyjuice potion is illegal unless approved by the Ministry of Magic, and I really don't think they'd approve of this."

"Not even if we asked nicely?"

"Not even if I asked nicely, and I'm the girl who freaking lived."

"True, so, are we really going to have to wear these freaking bandages for the rest of the year?"

"We could probably take them off every once in a while, when we're sure no one's around." I replied.

"Too bad you're not fat, then you could just say they're man boobs," Lisa joked.

"Is this really the time?" Hermione groaned.

"I'm done," I said, clipping the bandages so they wouldn't come off.

"Thank god," Hermione whispered, standing up.

"Just make sure to stay off the Quidditch teams, those bandages will be sure to strike up some interesting questions," Lisa said.

"No danger there, you know I hate flying," Hermione said.

"I was talking to Harriett."

"Girls, hurry up, you're going to be late!" Lisa's mother called from downstairs.

"We're coming mom, Hermione just has to put her shirt back on!" Lisa called back.

"I've got it," Hermione said, pulling the loose t-shirt she had chosen to wear over her head. "So, shall we go? It's going to be our first day at an all boy's school."

"Hey, I just realized, it's only ten, the train doesn't leave till eleven," I pointed out, looking at the clock on Lisa's bedside table.

"You know my mom, always paranoid about traffic," Lisa replied, "Let's go over our alibis on the way there." I grabbed my trunk which was leaning against the wall and headed out, Lisa and Hermione right behind me.
