The parts where they are thinking should be in italics, but I don't know how to do it.

“Do you love me?”
She always has to have these conversations while I’m trapped in a car. “Yeah.” A busty young blond with perfect teeth, tight jeans, and a pair of foxy, name-brand sunglasses – what’s not to love?
“Really?” she asked, dragging the 'e' and slightly cocking her head to the side. She wanted something.
“Yeah, what is it?” And he knew it.
“Well, my birthday is next week and –“
“I remember,” he lied, “what do you want?”
“Well, since you asked, there’s a fabulous emerald necklace at Romance Jewelers...” She had expensive taste.
“Isn't that store pretty expensive?” As if she would want something cheap.
“But it would look really great with my new dress.”
"We'll see."
The car in front of them suddenly slowed down; he slammed on the brakes. A pedestrian, a middle-aged woman with fishnet hose and too much make-up, started to walk across the crosswalk. She stopped half way and got into the car in front of them. A pro.
Neither of them said anything.
Hookers are like eBay, he thought, you get what you want for cheaper, sure, but they’re used, unreliable, and a high risk. Besides, he looked at his girlfriend, no hookers are that hot.
What a whore, she thought, it's disgusting how women sell themselves like that. Don't they have any self-respect?
They started driving again.
“You like my new dress?,” she asked, breaking the silence.
“Yeah, it looks nice,” he said. He didn’t like the color, but she looked good in just about anything... or nothing.
“Thanks,” she said.
“I’ll look into that necklace thing..." he said, pretending he had a choice.
“The emerald necklace - but I'll be happy with anything,” she lied.
“Alright.” He pulled over in front of a big brick building to let her out. This was where she worked, but what she did he didn't know. Not that it was a secret; he had just never bothered to ask.
“You’re the best, babe!” She got out of the car and waved goodbye - he wasn’t perfect, but good enough.

...

He walked into the store, preceded by an overly excited chime, and bumped into a middle-aged man on his way out. The man was well dressed, sporting a pair of freshly pressed slacks, a designer blazer, and an expensive comb-over. Neither of them apologized, each blaming the other.
It had been a slow day, and as the only shopper in the store he had the full attention of the sales staff. He looked through the necklaces on display, but couldn’t find an emerald one.
“Yeah....uh, excuse me..." he said to a hovering saleswoman.
"Can I help you find anything, sir?" she said. She was paid on commission.
"Yes, you can. I'm looking for a certain emerald necklace."
“Strange…”
“What?”
“Oh, nothing sir. That just seems to be a popular item today. Unfortunately, we only carry one style of emerald necklace, and we happen to have just sold out, but if you come right over here I'm sure we can find something perfect for that special someone."
"The emerald one matches her dress and –”
“No problem! We have this lovely green quartz necklace. It will match perfectly and it doesn't cost nearly as much as the emerald necklace would have - we can gift-wrap it for you if you'd like." She had not sold much today.
"Do you know where I can find an emerald one?" He knew what would happen if he gave her a green quartz necklace, and he wasn't willing to spend money for that.
"Well, we can order one for you, but have you thought about these other-" He hadn't.
"How long will that take?"
"About two to three weeks."
"Thanks anyway," he said.
"I'm sure we can find something else that she'll just adore," she said. She could feel herself losing a customer.
"I'm sure," he said. He left the store, followed by a disappointed clink.
The middle-aged man was sitting on a bench outside the store smoking a cigar. He seemed relaxed, his gold watch glinting in the sun. Oh his lap was a green velvet case.
“Excuse me, but what did you buy?” He asked the balding man.
“A necklace.” The man looked up, but stayed seated.
“Emerald?”
“Yup,” said the man, “last one they had.”
"Bastard." He turned to leave.
"I bought it for my wife for Christmas.”
“Merry Christmas,” he said. Christmas was three months away.
“…Of course, I have plenty of time to order a new one," the man said with a grin.
"Would you sell it to me?" He wasn't sure whether this was luck or misfortune.
"For a price..." The man slowly took another puff of his cigar.
"Not the same you bought it for I'm sure. How much do you want?"
The man pulled a piece of paper out of his pocket, scribbled something on it, and handed it to him. “Supply and demand, you understand," the man looked at his gold watch indicating that he didn't have a lot of time.
"Are you kidding me? This has to be like twice as much as it costs."
"Almost three times - man's gotta eat." He checked his watch again.
"Damn it..." He took out his wallet to see how much money he had. Do I really want to pay this much? I could buy a porn star for this price, he thought. He glanced at a wallet-sized photo of his girlfriend. I guess I don't really need a porn star with her anyway. "Here," he said, and he handed the man the money.
"Thanks a lot buddy, and here's your necklace." The man opened the small velvet case the store had given him when he bought the necklace, pulled out the necklace, and handed it over. The case must cost extra.
"I’m leaving before I realize how bad you ripped me off," he said, and walked back to his car. He called one of his girlfriend's friends to ask what day her birthday was and wrote it down so he wouldn't forget. Then he wrapped the gift in some Christmas wrapping paper; it was all he had around the house.
He picked her up from work for her birthday on Thursday. He almost didn't see her and quickly stopped in front of the crossing to avoid passing her. The car behind him slammed on its breaks. She let out a beaming smile when she saw him - excited about her present - walked halfway across the cross-walk, and got into his car.
They had a romantic dinner of low lights, fine pastas, and well-dressed waiters, and after dinner he gave her the emerald necklace, the perfect gift.
“I love you,” he said.
She smiled and looked at the necklace, “I love you too.”
