"TONY you are not LISTENING to me!" Ziva whisper-shouted across the driveway. She had just clicked Shira's car seat into the backseat, and despite her growing rage at her husband she was determined not to wake the sleeping girl.

Tony locked the front door and twirled the car keys around his finger victoriously as he walked towards her.

"Oh no, I'm listening Ziva, I'm just ignoring you." He answered. Ziva's jaw dropped.

"You are being insufferable!" she spat. "This argument is bigger than the two of us Tony! We have her to think about!" Ziva said in a loud whisper, inclining her head towards the car.

"Exactly." Tony agreed. "We do have to think about her. Which is why I am driving. Now let's go, we're about to miss our daughter's first doctor's appointment."

Before Tony had even reached the car door, Ziva snatched the keys out of his hand.

"Hey!" Tony cried out. Ziva promptly smacked him in the arm just as Tony realized his mistake and clapped his hand over his mouth. They both peeked into the still opened back door of the car and breathed a simultaneous sigh of relief when Shira didn't wake.

"Hey." Tony repeated, now in a hushed voice. "That's not fair; you can't use your ninja skills to win this!"

"Well what happened to the rule where I am always right?" Ziva hissed. Tony scowled.

"You said it yourself Ziva, this is bigger than us! We can't let Shira's safety be in question because of a rule!"

Ziva's tan cheeks were beginning to flush; Tony knew the argument would end soon one way or another.

"Shira's safety! You think she is unsafe with me? I am her mother!" she argued back. Her voice was becoming dangerously loud.

"Ziva the whole world knows you can't drive! You once tried to bribe me into taking credit for an accident because your driving record couldn't take another mark!"

"And what about you?" she countered, stepping closer to him. Tony flinched; wife or not she was still intimidating. "You are a car killer Tony!"

"What? I am not! I-"

"Tony how many cars of yours have been destroyed?" Ziva demanded.

Tony faltered. He would rather not count.

"Well, how many speeding tickets do you have?" he fought back. Ziva balked. In all honesty she had lost count, but Tony certainly did not need to know that.

"That's not the point! None of my cars have been, been, demolished before!"

"Look," Tony grunted, "one of those times somebody was trying to kill me, and once someone was trying to kill YOU!" he exclaimed, his eyes glancing again nervously at the car. "Not my fault!"

"It does not change the numbers Tony." Ziva said calmly as she crossed her arms across her chest. Tony exhaled slowly and reached for his phone.

"What are you doing?" Ziva asked, her expression torn between annoyance and confusion.

"I'm calling McGee. Clearly this argument is going nowhere." Ziva narrowed her eyes, but then shrugged. He had a point there. Neither one of them was going to give up any time soon.

"Well, at least there is one thing that we can agree on." She offered, looking back towards their daughter.

"Rule thirteen," Tony said before they whispered in unison, "Shira never drives."
