The doorbell rang. Meredith let out a frustrated moan. She REALLY hated that thing.

"Maybe I'll dismantle." She thought as she got out of bed.

Izzie and Alex had gone out to Joe's to get a drink. She wasn't sure if she should expect them home or not. More if she should expect Alex home. If Izzie were to have a one-night-stand, she would bring it her. She turned on the light and glanced at the clock. It was only a little past nine and she wasn't tired but she just wanted to lie in bed and think. She opened the door to be met with the very annoyed glare of Derek. She pulled the door so on the width of her body was the crack of the door.

"What?" She said with the lack of emotion.

"No hostility, right?" Derek said bitterly.

"No hostility," She said. "Why are you here, Dr. Shepherd?"

"You are my sister's resident."

"Yes…"

"You still have no right to yell at her like that or put her, Dr. Peep, and Dr. Johnson on-call. That's a 48 hour shift."

"See here's there problem. Right there. You came over to my house, at night, to yell at ME. You come over here as an ex-boyfriend with a sister working under an ex-girlfriend. When you go to the hospital walk down the halls and look around, everywhere you look you will see interns being yelled at by their residents. It's our jobs. Also pick an intern under any resident, they ALL have 48-hour shifts. Just like Alex, Izzie, Christina, George, and I had when we started under Bailey. So I will yell and make them work long hours. I will go in if there is a page. I will do whatever needs to be done so they'll be a good doctor. And if every time I yell or make them work long hours, you come over here, it's going to be a long year for both of us. Because when I get back to work… Nothing is going to change. If she can't take the heat, you can tell her to get the hell out of my kitchen because that's how it's going to be. And what I can't understand is… You were perfectly fine last year when Bailey worked us to the bone or any resident for that fact work the interns to death. So why this year so different? And if you say your sister is in the program, I swear to god, I will hurt you. And let's get one more thing straight. Inside that hospital, she is not your sister. You are not her brother. I'm not the dirty ex-mistress that turned into girlfriend now ex-girlfriend. She is the intern. I'm the resident. You are the attending. Why is that so hard to understand, Dr. Shepherd?"

With that, she stepped back and shut the door.

She walked into the kitchen still a little ticked off that Derek would come over here to tell her that she's being rough on her interns. Interns are suppose to have it rough that what makes them interns. They all need to get used to it. She shook her head to rid it of those thoughts.

She started to munch on a few cookies and drink some milk. The doorbell rang again.

"Should have dismantled it when I had the chance, damn," She thought.

She walked back into the living room and opened the door. There stood Mark.

"Hey," She smiled at him.

"Hey," Mark smiled back as she let him in. "You doing anything?"

"Nope," She followed him to the kitchen. "Beer?"

"Yeah, thanks," He said as he sat down at the counter.

"Uh-huh," Meredith said and put it in front of him. "I had an unexpected visitor."

"Is that code for a period? If it is, I don't want to know," Mark said playfully covering his ears.

"No, somebody came by," She laughed.

"Who?"

"Derek"

"Derek? What did he want?"

"He wanted to yell at me about being rough on his sister."

"That's the point of a residency."

"I told him that. I think, he got to point." He smiled at her. She smiled back and took his drink. She sipped it and put it back in front of him.

"Hey," Mark said.

"Thank you very much," Meredith smirked.

"You are so not welcome!" Mark said.

Meredith laughed, causing him to laugh.

"Damn her laugh is intoxicating," He though to himself. "Stop thinking like that, Sloan. You don't even know if she likes you."

"So how are your three devils," Mark said with a smirk.

"Hell. Between their complaining and Derek's, I was so close to calling the whole 48 hour thing"

"They'll get over it"

"God I hope so"
