"But you could be part of their solution," says Nima, in the curious tone of one who hasn't had to explain why giving is the greatest thing ever too many times before.

Mai's mention of Zuko goes a little ways towards explaining things - Zuko, Nima knows, is the Fire Lord of the future who will end the war his great-grandfather began to destroy her people. If the Fire Lord is this girl's close friend, then she is a noble, and nobles shelter themselves from the concerns of the poor. A humble nun like Nima has not had many chances to meet with nobles, back in a time when airbenders, though rare, were hardly impossible to come by.

"Throw knives? There must be a game like that around here somewhere." Or maybe there's a shuriken-themed club that Mai would hate less than the last one.
