[To be honest, Bolin wasn't even making a slight about his age. He can actually relate because he's been trying to figure out how to metalbend for about as long, really, all with no success. He was just surprised that Bumi would even want to learn meditation when he wasn't an airbender.

[But sure, Bumi is kind of old, let's be honest.]

Well, I mean, of course they did. Avatar Aang was all about it. Meditation, that is. [Yes, he is kind of the Team Avatar fanboy; he's read a lot of stories.] I mean, even if you weren't an airbender, did Aang try to teach it you back then still?

[Because he wants to know all the details. You're just lucky he knows who both your parents are, Bumi.]
