Give me a ship and I’ll tell you:
Who cooks: Caroline because Kol is a lazy bum, but sometimes he likes to bug her by kissing her from behind and tasting her food before it's done.
Who does the laundry and other chores: Caroline, until she's had enough and dumps a month's worth of dirty laundry on top of his head. Kol's surprisingly good at keeping the bathroom clean though.
How many children do they have: Zero; every time Caroline brings it up, she's shut down but is slowly figuring out that Kol's just afraid because of his own family issues. They have a few things to get past before they bring kids into mix.
Who’s more dominate: They push each other, but they also give into each other too, so it's hard to tell. Nine times out of ten, it looks like Kol is, but that one time, Caroline really makes him work for it.
Favorite nonsexual activity: Getting drunk and sending each other funny text messages. They also have an affinity for crashing parties they're not invited to.
Their favorite place to be together: Big cities. When Mystic Falls gets too be too much for them, they love getting lost aka losing each other and finding each other again in a big city.
Any traditions: Their anniversary is sacred, they're the only ones who know the exact date so no one can intrude and they do whatever they want that day as long as they don't argue and they're together. It's their perfect moment.
Their “song”: I'm Yours by The Script
What they do for each other on holidays: Caroline changes the subject if things start to get heated for Kol at the Mikaelsons'; Kol squeezes Caroline's hand under the table when her parents get to be too much at Thanksgiving; midnight kisses on New Year's Eve are their favorites and they try to have one for every timezone.
Where did they go for their honeymoon: Caroline has her fingers crossed for a tropical island even though Kol only seems to "entertain" the idea, he actually already bought a beach house in Fiji just for them.
Where did they first meet: The Mikaelson ball; Kol still thinks he could have gotten Caroline to go much easier than Klaus. Caroline agrees.
Any pets: They had a cat, but when she passed, Caroline didn't have the heart for another although Kol tried to convince her that it was okay. She was only okay with it when Kol finally snuck a kitten into their bed and she woke up to little meows and a collar that said 'Kol J.R.'
What do they fight over: Everything and anything, it's quite amazing how many things can set them off. But then, they're also pretty sure that they have the best make-up sex in the entire world, so it balances out.
Do they go on vacations, if so where: They don't have traditional vacations, per say -- Kol just kind of throws Caroline into the car whenever he wants and after the initial irritation wears off, she has to admit it's weirdly romantic being kidnapped by her boyfriend.
