So, I was feeling a bit bored, and came up with a few of these little conversations that could fit into the series at various points. I'll upload some more later, probably.
And, if anyone's bothered, 'Avatar: The Last Airbender' really doesn't belong to me. I would have thought it obvious, but you never know.
Not Very Funny
"What are you chuckling about?"
"Just then- you started laughing."
"Oh." Sokka grinned guiltily. "Sorry, I was just thinking."
Aang gave him a quizzical look. "About what?"
Sokka sat up, being careful not to wake his sleeping sister who had rolled over onto his feet. Sokka often mentioned to her the dreadful noises she made- and was making at this moment- while she was asleep. She always denied it.
"I was thinking about the other day. You know, in Omashu."
"What, the part where you got covered in a giant piece of candy?"
"No, before that. When we went on that slide- postal service… what ever you want to call it."
"Oh." Aang nodded. "Yeah, I remember." He grinned over at Sokka. "That was fun, wasn't it?"
Sokka nodded. "Yeah. But it made me think about something."
"Well; you're just a kid, aren't you?"
"Well, technically, I'm over a hun-" Sokka held up a hand.
"That's not the point."
Aang looked sulky.
"My point is; aren't you kind of a bit… young? Y'know… to be saving the world and all that?"
"I suppose. But who else is gonna do it?"
"Yeah, I know." Sokka sighed. "And I bet you will be able to do it. It just seems a shame- to have all that responsibility when you're still about five years ol-"
"A hundred and twelve." Aang corrected him.
"Whatever." Sokka yawned, lying back down. Aang stared up at the sky.
"It's not actually very funny, is it?"
"No. Not really."
