Of course, the next day, her birthday turns out to be global news.
She is - mercifully - the first to know. The monks from the nearest temple show up at the crack of dawn on a sky bison and report to her in grave voices about a day she can't remember when she was a year old when she grabbed the right three toys out of a selection of hundreds.
Beila's not that surprised. She didn't expect this, but there wasn't such a huge candidate pool, really, she knows four other airbender girls close in age. She nods, and agrees to find herself a waterbending teacher immediately, and she's supposed to check in with a nun periodically and she carefully reserves judgment about whether that's going to happen.
Then they make the general announcement and the whole world knows.
She doesn't even ride Liqing to school, arriving there on her glider instead, because she fears the crowds will spook the birds.
"It's not like I'm any more likely to start accidentally firebending than I was yesterday," she points out. "Thanks for the carving, by the way, it's really cute."
"No, seriously, did something happen, is something wrong, I totally have license to go around fixing wrong things now if something is wrong."
"Yeah, it's all over the news, I glidered in, Liqing would freak with all the reporters, I'm just glad they're keeping out of the school building proper," laughs Beila. "What's the matter?"
"I'm still the same person. I've been the Avatar since I was born," Beila says. "They just didn't tell me till this morning."
"I'm not, like, overwhelmed with people who wanted to be my friend before knowing I was the Avatar," Beila points out. "I'm not saying I can never make new friends, but they'll be a little trickier to vet, you know?"
"So is this a - a 'I am concerned in spite of your reassurance that you may unexpectedly firebend' or a 'I want some distance from your incipient fan club' or a 'get away from me, spirit-touched creature, I certainly do not want to go flying with you next weekend' or what?"
