Bold Italic: flashback

Paul P.O.V.

The whole point of their Casual Hook's was to relieve stress and release energy- both good and bad. According to Derek, if they didn't get to do this, the house goes to the deep end. Lizzie and Edwin go into another one of their strikes, George and Nora would start to doubt their parenting skills and overanalyze each small thing and Marti . . . well she would stay the same, but you get the point.

Derek P.O.V.

I honk the horn for the umpteenth time as I wait for my step sister in the driveway. For some reason it takes her five minutes to finish homework and yet an eternity to get ready. I honk the horn again.

"Casey let's go!" I shout out of the window. Looking back at the front door, I see her grade ten self scamper to the car. Her hair is in a neat bun and she's wearing a different outfit than earlier. As usual though, her oversized book bag hangs off her shoulder and shoelaces are untied. And she wonders why she always falls?

"I'm here okay." She huffs jumping into the Prince.

"You went back into the bathroom didn't you?" I question testily, staring at her.

"Because of a certain athlete, I had to do an emergency touch up." She expresses looking me straight in the eye.

"You're shoes are untied." I point out, ignoring her statement and pulling out of the drive. She bends down in her seat, beginning to re-lace.

Casey P.O.V.

And so it begins: the Car Fight. I think to myself while tightly tying my shoes.

It seems like whenever we have what I call a'Casual Hook" in the morning, an argument insues. I've pointed this out to Derek, but he just says: "You're just overthinking again Casey. We're Derek and Casey- all we do is fight." Secretly I think he believes I'm right, because in the car ride after we casually hook in the morning, he either changes the subject, turns up the radio or asks about the weather. I'm used to it by now, but it's still annoying.

Derek P.O.V.

Out of the corner of my eye, I see her finish tying her shoes and pull out a book from her book bag. The topic of what happened this morning, clearly out of her mind. I sigh to myself inwardly, happy to have escaped another of Casey's Car Fights (for some reason whenever we "Casual Hook" as she puts it in the morning, she becomes majorly defensive. I try to clear my head and refocus on driving.

"Derek I have to finish packing my bag and not to mention I promised Max I'd print our book report." Casey complains while running back and forth across her room gathering stuff, and placing them into a blue book bag on the side of her bed. I lay back comfortably on the bed, watching her hysteria in enjoyment.

"It'll take two seconds to pack and you can print the report during." I express in an obvious tone, but she just shoots me an annoyed frown. I get off the bed and walk to her. "What's five minutes?" I persuade.

Casey P.O.V.

It was more than five minutes. I snap at myself, unable to keep my mind on my book.

He does this all the time. Lying about how long it'll be. Unfortunately I guess I can't exactly blame him. I mean I foolishly believe him- always. And why is that? I mean he is Derek Venturi, the King of Liars. If i know he's a liar, why take his word? I put the book back in my bag, giving up on reading.

"What's that?" Derek asks pointing at my neck. We were at a red light and school was two blocks away. Quickly I pull down the mirror flap and peer over the area.

"A hickey!" My eyes become glued to the perfectly circled bruise located visibly below the side of my chin. Before the light turns green, Derek reaches into the glove compartment and takes out a tube of makeup foundation.

"Cover up Princess." I take the foundation out of his hand without diverting my eyes from the mirror.

"You know if you hadn't rushed me out of the house, I would have been able to see this before." I snap. "And can you not suck on my neck?" I add impatiently while applying the hickey remover.

"Can you not grab my back?" he retorts. "You're hands are ice cold. Haven't you been doing those hand exercises I told you about?"

"Apparently they don't work." I rejoinder, letting loose my hair from its tight bun. "And I'd finally had the perfect bun to." I cry in anger.

Derek P.O.V.

"The point in getting that foundation was so you wouldn't have to wear your hair out." I remind her, not hiding my irritation on the matter. She goes into her book bag and reaches for a brush.

"But I still feel like it's visible if I don't." she explains. "It doesn't hurt-"

"'-to be careful'." I finish for her. "You've only told me a thousand times." We drive into the school parking lot and I easily park in my official parking spot.

"I really hate this." She states frankly as she brushes her hair evenly on both sides.

"Of course." I sarcastically agree while unbuckling my seatbelt. Casey shoots me a teed off look and gets out of the car, slamming the door behind her.
