Elisa picked the prompt "door." Heh. I don't own NCIS.
"Would it really rain cats and dogs, Tony? No. That is not logical at all. So why do you say it?"
"It is an idiom, Ziva. It's just a phrase to say that it is raining hard."
"People cannot say that it is raining hard?"
"No they can-"
"See, this is why your American idioms confuse me! You have to make things very difficult, do you not?"
"They are not confusing, Ziva."
"Yes, Tony, they are confusing!"
"Well," Tony said calmly, looking at Ziva over the table, "maybe that is because you know too many languages."
Ziva laughed and shook her head. "No, Tony. You are wrong. I do not know too many languages," she said.
"Arabic, Spanish, French, English, Hebrew, Turkish, Italian, German, and Russian. That is not too many?" Tony said, ticking off each language on his finger.
"Don't forget the language of love," she teased, winking at him over her slice of pizza.
Tony chuckled and then watched her eat. He was opening the doors of the English language to her; he was teaching her everything he knew about idioms. She needed to know them anyways, because idioms were a large part of his vocabulary and they were her weakest spot. She needed to understand the idioms so she could understand him.
"So, Tony," Ziva said, bringing the senior field agent out of his thoughts.
DiNozzo blinked and looked at her, a smirk dancing on his lips. "Yes, Ziva?"
"What other idioms do I mess up?"
Tony smirked and finished his piece of pizza, taking a drink of his beer. "Well, let's see. You mess up a lot of them. Should I start from the beginning?" he teased, looking at her.
Then, Tony started explaining to Ziva everything that she had previously messed up before. Tony couldn't help but smile while he was explaining things to her. He loved explaining the idioms to Ziva, and he wouldn't change anything.
