Anna loved going to the market place in town. As a child, the market was an unending source of adventure and excitement. In addition to this, the young Princess had a friend that worked in the bustling market of Arendelle. Kristoff was a young ice harvester, only a few years older than Anna herself, that the youngest Arendelle royal had befriended on complete happenstance.
Running off from her handler, Anna had scampered around the different vendors and temporary stalls, one thing and then another grabbing her attention. After exploring for a while, the five-year-old had started to get a bit bored staring at one of the vendor's jewelry - she liked them well enough, they were pretty and caught her eye, but her attention span was just too small at that age to stay on one thing for very long.
That was when she met Kristoff. As she skipped out of the jeweler's shop, Anna had spotted a boy with a little sled of ice and a reindeer calf. Having been to the market numerous times in her young life, Anna had seen grown up harvesters before, but never one so close to her age - and with a reindeer, too! Anna had never seen a reindeer before, not outside of the illustrations in her storybooks, at least.
Obviously, Anna had to make friends!
She had gone over, promptly tripped, and knocked into the boy. After a brief argument - You pushed me! Did not! Did too! - the two became unlikely friends. A Princess and an ice harvester, an optimist and a pessimist.
It was this optimistic outlook Anna had that came into play on this specific day in the market.
Gerda, Anna's chaperon for the day, had long since become accustomed to making a stop by the young boy's spot in the market place; she would speak with the spice vendor across the way, keeping an eye on the young Princess while doing some shopping for the castle's kitchen. The older servant didn't dislike or distrust the harvester boy, but her duty was to Anna's safety while away from her parents, so she never strayed far from her young charge's side.
"Hello, Kristoffer!" Anna greeted jubilantly, hopping over to her friend's side, Gerda watching from her station just several feet away.
Kristoff scowled down at the cobblestone street, grumbling something out under his breath.
Anna frowned at this, repeating her greeting, "I said, hello."
"Yeah, I heard you," Kristoff huffed, scuffing his boot against the ground.
The redheaded girl crossed her arms, and stomped a little foot. "Well, that wasn't very nice!" she snorted, not even caring that it was "unladylike".
Kristoff rubbed his nose against his sleeve, snuffling. "...Don't care."
This was not the sort of response Anna was looking for. "Why are you so grumpy today?" she asked, staring up at the taller boy. He was acting like her sister, not telling her what was upsetting him, and Anna wasn't going to be ignored.
The blond boy scuffed his boot against the cobblestone again, his mouth pursed to one side as he thought about answering her or not. "...Some stupid kids came over here earlier, a couple years older than me, I think...They kicked over my sled, and ruined my ice, so I can't sell it," he finally replied.
Anna's expression was quick to change at that. "What?! Why would they do that?!" the little girl demanded, taking note of his unusual lack of ice to sell that day.
Kristoff only shrugged, folding his arms over his chest crossly.
"...Well, do you have any ice left?" she asked, stepping closer to him.
"Yeah, but it's not good anymore. It's all...chipped and broken up."
Anna latched onto Kristoff's side in a hug, grinning up at him. "I'll buy it, I'll buy it! But you gotta promise not to be grumpy anymore today, so we can play, okay?"
