Sorry this has been so long! I actually started this chapter ages ago, but only managed to finished it today. Hope you like it.
Anna, being the wonderful roommate that she was, tried to keep things clean. She tidied up after herself when she used the kitchen, she washed her dishes less than 2 days after she made them, she dried the floor in the bathroom after showering, she kept her dirty shoes by the entryway and ensured that her room was as tidy as she had time for. She occasionally dusted, swept, and mopped. She cleaned up Sven's dirty paw prints when he went on walks in the rain.
Kristoff was a great roommate! No really. He kept the noise down, he didn't walk around the apartment in the nude, he ensured that if Sven was dirty there was a bath, he made sure Sven didn't pee in the apartment, he usually made sure not to leave his sooty coat or boots in the way. He did his dishes (and hers, more often than not), and also dried the bathroom floor after showering. He usually bought groceries for the both of them while Anna made the list and took stock.
Unfortunately, the two of them had slightly different opinions on what made a person a really great roommate and, as roommates often do, they had the occasional disagreement. Anna wanted him to clean up around the apartment a bit more, because the stack of pizza boxes in the living room was reaching unimaginable (and smelly heights), people kept tripping over the empty cans and bottles accumulated in the hall, and his room was atrociously messy (and possibly creating an unpleasant miasma. Kristoff wanted her to mind her own beeswax, the state of his room was none of her business, and there was nothing wrong with the tower of pizza (boxes).
So, the two of them fought over it.
It had started subtly at first. Anna pointedly bagged up the bottles and left them by the door (Kristoff had three night shifts and on the last morning he proceeded to epically trip over the bags, pull down the coat rack, and ended up falling asleep on top of them. They never did make it to the recycling depot). Anna left a broom and a bottle of air freshener just inside his room (Sven knocked over the broom and the bottle of air freshener mysteriously disappeared, never to be seen again). Kristoff started leaving his door open and purposely not making the bed. Kristoff stopped buying KitKats (Anna loved them and Kristoff was ambivalent towards them. Anna started buying big boxes of Halloween candy). Anna bagged up the pizza boxes and put that bag by the door too-with the recycling (Kristoff moved the back back to the living room because it was blocking the way out).
It came to a head one night when both of them were lounging in the living room, Anna marking assignments while Kristoff watched reruns of Parks and Rec.
"You know, it wouldn't kill you to take out the trash." Anna motioned at the bagged up pizza boxes with her red pen.
"There was nothing wrong with the tower of pizza." Kristoff rolled his eyes at the familiar argument.
"It was starting to smell!" Anna glanced up at him with a frown, "Its probably a fire hazard too, you'd think you would be more worried about that, considering your occupation."
"It wasn't in the way of the door," He glanced away from the TV, "The recycling has been since you bagged it up though."
"You could always take it to the recycling depot." Sven, having been curled up on the rug, looked up in concern.
"If you want it to go to the recycling depot so bad, why can't you do it?"
"Why can't I do it?" Anna set aside the math tests, "What do you mean, why can't I do it? I do all the cleaning up around here. I don't think you've touched a broom since I moved in! You leave crumbs everywhere and if I hadn't been cleaning up around here, you'd be dealing with an infestation!"
"Oh come on! I clean up after myself! I've been doing all the dishes for ages!" Kristoff turned towards her, "Don't think I haven't seen you, putting your dish beside the dishwasher. Dishes get clean when you put them in the dishwasher, and they definitely don't put themselves there! It doesn't help to put a dish beside the dishwasher! They don't get clean there!"
"I do the dishes! And I sweep and mop the floor, I can actually see the carpet in my room and I'm not the one who leaves the lid of their tooth paste off! Every time!" She huffs, sitting straighter to try and intimidate him (not that she could, even with him slouching on the couch), "You could at the very least make sure to do your laundry before you're left with one clean sock out of the lot!"
"You're one to talk about laundry! Last time you did laundry the entire place smelled like lilacs for weeks! Sven's nose swelled up and he tried to run away when I took him for a walk!" Kristoff sat up, towering over the smaller girl.
"We said we weren't going to talk about that!" Her face flushed, "Besides, you can't talk about smell, your room smells like a pigsty! My sweaters are forever covered in soot because of your stupid coat, and if you even try to deny the mess I found in the bathroom after Sven's last bath I will- I will- I'll do something! And you won't like it."
"That wasn't my fault! Mostly," He glared down at her, "And my room smells perfectly fine, you're just being ridiculous."
"You can't deny the smell! Even your mom agrees with me," Anna's ears were red with anger, and she straightened her back, "And it was so your fault!"
"You're completely off your rocker!"
"Urgh! Kristoff you are so..! Argh!" Anna sprung off the couch and gesticulated wildly with her hands. "I can't even-!"
Kristoff stood as well, crossing his arms as she sputtered, then stalked to her room, slamming the door behind her.
"Well that didn't go well." Sven was looking up at him from under his paws.
"It's not my fault! … Well no… Okay, fine. I could probably do to clean a little more often…. Or at all."
Sven stared at him, mute.
"Fine! I'll apologize in the morning." He threw his hands up in the air and stalked to his own room, leaving the door open for Sven.
