Dahilarën
A Dahilarën is a kid who's supposed to be awesome, and they usually are. They're polite, but they're also a bit of a know-it-all.
"You're polite. I'm polite. But I'm also a know-it-all. So I win."
"I don't just know things. I know them better than you do."
"I'm polite. You're not. That's how it works."
