This one is set in that Keeper of Kitties story I wrote a while back.
Demotic
"Denoting or relating to the kind of language used by ordinary people; colloquial."
"I don't have an uncle named Bob, though," Lucy said thoughtfully.
Laxus groaned into his hands. The jester was snickering beside him, mindlessly playing with the cats that were swarming him, while Evergreen and Freed were getting on with their jobs.
Since taking the job as the kitten caretaker, and accepting the fact that he really fucking loved his job, Laxus had ended up forming a close bond with the princess. He wasn't too fond of the cats even though he'd been there for half a year, but he was fond of the princess, and he as fond of the moments where he got to spend time with all of his favourite people. It didn't happen very often, and it was usually late at night once the king had retired and once the staff all went to their quarters.
After spending more and more time with Laxus's friends, Lucy hadn't been able to help but notice they spoke in a slightly different way to her. There were phrases she didn't quite understand, inside jokes she couldn't begin to wrap her head around, and… Well, Lucy was inquisitive and liked to learn, so she asked what they meant, and most of the time, it ended with Laxus shaking his head at her and spending fifteen minutes trying to explain them to her.
That particular night had begun with Bickslow, the jester, talking about something that was sure to revolutionise the world as they knew it, and then saying something about an uncle named Bob, and of course, Lucy had decided to ask about it.
"I don't have any uncles, actually," she added.
"That's not—" Laxus sighed, rubbing his temples. "No one has an uncle named Bob, alright?"
"I'm sure someone has to. But what does that have to do with Bickslow's idea? Does Bickslow have an uncle named Bob?"
"Wouldn't have a clue!" the jester chimed in.
"Look, it doesn't actually have anything to do with uncles at all," Laxus said.
"Then what—"
"It's just a saying."
Lucy rolled her eyes. "Well, I know that much," she mumbled. She wasn't an idiot. "You're not a very good teacher, you know."
Freed snorted, earning a glare from his blond-haired friend. He knew he wasn't a good teacher. That wasn't his job. Although at that point, Laxus wasn't really sure what his job was. It mostly seemed to be keeping the princess company when her father's dog wasn't watching her.
"It's like a, ta-da!" Bickslow offered, patting the calico cat that had climbed up onto his shoulders.
"Ta-da?"
"Yeah, like… Like everything is all done, you know? Like, you're set."
"Oh," Lucy said. "So it's like, the end?"
Bickslow shrugged. "I guess so."
"Really? That's what makes you understand it?" Laxus muttered.
"Bickslow doesn't get huffy with me when I don't understand," Lucy huffed. "You just groan and sigh at me."
"I do not!"
"You kind of do," Evergreen mumbled.
Laxus huffed, crossing his arms and looking away, ignoring the cat that was slowly sprawling across his lap. At least the cats didn't tease him.
