"It's more like a penname than a nickname, I guess," Zuko says with a shake of his head. It's hard to explain things he only knows the functions of, himself. "Imagine it like there's a tiny town bulletin board inside the phone — it's kind of like that. But everyone can interact from far away at any time by posting on it, or responding to things that were posted on it... Whatever you post, there's a name that appears beside what you say, like a signature. That's your username. And anything said that way is called being 'online.' I don't know what it means, that's just what everyone calls it."

The tiny town bulletin analogy has not flown over well in the past with others, but this is how Zuko's made it make sense. Maybe Iroh can jive with these same sensibilities. Truth be told, Zuko's proud of how much he's gotten comfortable with these things, though, that he's needing to backtrack to his initial 'ink, stamps, pamper roll, magic mini-bulletin board' mentality he'd first understood things by. It seems so long ago now, all of a sudden. He lets out an accidental little sigh at the feeling as he digs out the tea leaves he'd brought along and is now put to the test to really prove himself. Technology is not as impressive to Uncle as tea, that's for sure.
