Disdain
When Aang danced with Onji, Toph laughed at their awkward movements. And then when Aang danced with Katara, Toph nearly fell over from cackling. Maladroit and ridiculous, those two complemented each other beautifully.
Like two left feet shackled and bound and left to spin on a pivot.

"Would you like to dance?" Zuko said—teased.
"Sparky," she said, "I'm blind."
"Don't make excuses, I know you can dance perfectly well."
"You're right, I just don't want to dance with you. Might get some princely germs on me. You know, the ones that never wash off."

When Aang and Katara married, Toph really did fall over. Broke her throat, broke her lungs, broke all the laughter in the world.
He stood one head shorter and a mile more callow.
And Katara, like the epitome of the Mother.

"What an awful pair they make," Toph sang for all to hear. For all to see how absurd this was.
But only Zuko heard and only he had sense to agree. "Yeah, kinda like a fish and a bird."
"Exactly that."
(And only Zuko had the ability to make a pun as boring as that.)

Toph had a harsh-wielding desperation frenetically going crazy. But that was a secret, and she was never going to tell.
But Zuko was a good friend and had a good ear too.
"Sparky, I have something to say. I'm not jealous of Katara, and I don't like Aang. In fact, I don't even like boys. I liked your sister."
"Okay," Zuko shrugged. After all, that had been obvious.
