"Okay what's the atomic symbol of Potassium?" Mark questioned as he skimmed through our science books.

I threw my mini football back and fourth in my hands. "K…next one?"

He sighed, rolled his neck, then said, "Radium…"

"Rd?"

"Yep…I'm tired of elements Shep, let's do something fun." He rolled off the bed, grabbed my binoculars off my nightstand and ran towards the window.

"Mark, what are you doing?"

He brought the binoculars up to his eyes and grinned. "You have some hot neighbors!"

"ARE YOU SPYING ON THEM!?" I snatched the glasses from his hands and threw it on the nightstand. "If they ever caught you, you'd be arrested for stalking and SPYING!"

"Oh come on Derek, they're never gonna know plus they're not naked…" a mischievous grin appeared on his face, "Yet…"

I rolled my eyes in disgust. "You're pathetic Mark."

He began to say something then focused his eyes outside the window.

I slowly sat down on my bed, causing the springs to creak. "What are you looking at now, a naked 15 year old girl?"

He turned towards me, a huge smile plastered to his face. "Actually…I'm looking at Meredith kissing some dude."

I jumped off of my bed faster than I have ever jumped off anything before, and ran up to where Mark was leaning against the window. And sure enough, there was Meredith…practically making out with my neighbor across the street. "Oh my God…that's RYAN STUPINSKI! He goes to the stupid prep…"

"You know him?" Mark questioned.

"He's my neighbor…we've never gotten along well though."

"Why?"

"When I was 13, I asked his 12 year old sister out, and well…yeah, he's hated me ever since."

The smile on Mark's face softened. "Well now he has your girl."

"What? No he doesn't…I'm with Addison."

He raised an eye brow. "Not in your dreams…"

"Okay shut up now."

"Dude, what are you doing? Go down there, punch him out, and give Meredith one, hot-"

"No! There will be no punching and most definitely no kissing." I looked back down at Meredith, and this weird feeling overwhelmed my stomach. I thought she broke up with her boyfriend. I thought she was single. I thought she was "hurt". Turns out, I was wrong. And trust me; there is nothing worse than being wrong.

After school the next day, I waited patiently for Meredith at the graffiti infested wall. I checked my watch, she was ten minutes late. "Come on Meredith, where are you…" I took out the paint and brushes then placed them neatly against the wall.

"Hey…"

I looked up and saw Meredith walking towards me. "About time you got here…your ten minutes late!"

"I know I know…I had to stay and do some stupid extra credit thing for math. I swear Mrs. Burns is-"

"Look Meredith I'm not here to make small talk, I'm here to work so come on, lets just get this done…and the next time your going to be late, do me a favor and let me know…" I didn't mean to come off so cold, but I couldn't help it. She basically lied to me.

"Woo…what's your problem?"

"Oh nothing, I'm perfect actually. I'm a great boyfriend, a great friend, I don't lie, I'm not a man whore…"

"Okay, where are you getting with this?"

I paused then stared at her for a moment. "I'm just saying…I don't jump on every girl I see."

"What's that supposed to mean? Are you saying I jump on every guy I see?!"

"I saw you with Ryan last night…" The name in itself made me want to vomit. "I thought you were hurt and sad, well I guess I was wrong. So that only doesn't make you a slut, it makes you a liar…you're a slutty liar." Oh man, I was so going to regret this…

Her cheeks were burning red, and her eyes were a fierce, dark gray. "OKAY FOR YOUR INFORMATION, RYAN HELPED ME THROUGH A LOT AFTER MY BOYFRIEND CHEATED ON ME! AND HE IS NONE OF YOUR BUISNESS! GOD DEREK DOES THIS AMMUSE YOU? PUTTING OTHER PEOPLE DOWN TO PLEASE YOURSELF! YOU KNOW WHAT…JUST BECAUSE YOUR UNHAPPY, DOESN'T MEAN YOU HAVE TO MAKE ME UNHAPPY! SCREW YOU!" With that, she stormed off…leaving me alone.

"Mr. Shepherd, what is the answer to number 15?" Mrs. Burn asked.

I didn't answer, I barley heard her. I was too busy thinking about Meredith and our stupid fight caused by stupid me!

"Mr. Shepherd? Mr. SHEPHERD?"

I looked up. "Oh uhm, sorry…I got 132."

She shook her head in the 'I'm extremely unhappy with you' sort of way then placed her hands on her thick hips. "Pay attention Derek…can anyone tell me the real answer?"

Addison hesitantly raised her hand, her eyes fixed on me the entire time.

"Mrs. Montgomery?"

"I got 142."

"Nicely done." As the teacher turned towards the black board, Addison tapped me on the shoulder.

"Everything okay, Derek?"

I nodded, avoiding the look in her eyes. "I'm fine."

"You sure? You seem so off."

Finally, the bell rang. I gathered my books then kissed her. "I'm fine Addie, really I am."

"Okay so let me get this straight…" Mark popped a French fry in his mouth as I spilled everything about Meredith (not in the presence of Addison of course), "You called her a slutty liar?"

I nodded, shame taking over my face. I was an idiot.

"Hmmm, well, no offense, but that probably wasn't the best thing to say to her."

"I KNOW MARK!" I could not believe him. Wasn't he supposed to make me feel BETTER about myself?!

"Okay, okay…I'm not judging, I'm just trying to wrap my mind around this. I mean you shouldn't be this jealous…you're with Addison and she's with Ryan, no big deal."

"But it IS a big deal to me! I don't know why, this is so effed up!"

Mark placed his hand under his chin. "I'm so sorry man…you really got yourself into a huge mess."

"Mr. Shepherd?"

I looked up to see none other than Mr. Webber. "Yes, sir? Is something wrong?"

He nodded. "Yes, Meredith came by my office today and requested a new partner. She wouldn't discuss it but she seemed pretty adamant about having someone else to work with. Now I don't know what happened, but I have to reassign you."

"W-what?!" A new partner?! This couldn't be happening!

"I'm going to assign you to Izzie Stevens, got that? You'll be working with her from this day forward."

"But…do I get a say in this?"

He looked at me long and hard. "Should you get a say in this?"

I felt my cheeks flame up. "Uhm, no sir, I shouldn't…"

"Alright then…I'll see you later Derek."

I turned towards Mark. He gave me an apologetic smile then patted me on the back. "Sorry…"

Wow, I really screwed myself over this time.
