Summary: Azula is good at everything important.

Useful

Azula threw down the biwa in disgust.  It clattered against the floor of the music room and jolted Zuko out of his own playing.  The strings popped and burst free from their tethers as Azula shot to her feet, pelted the pick across the room.  It stuck in the wall and vibrated like a knife blade.  Zuko stared at it until it stopped moving.

"Please, Princess Azula," the music master smiled, tight lipped, voice too calm.  "Come sit down."

"No!"  She spun around in the doorway, the tendons in her arms popping like she as going to pull the walls down.  "I don't have to!  It's not going to make me a better firebender, or help me conquer the Earth Kingdom, or rule the Fire Nation, or... anything!"

The pounding of her feet grew quieter and quieter, and Zuko just eyed the music master and waited to be noticed again.

Azula didn't give up.  She never gave up.  And she was always good at everything.  All the sour notes- She just didn't care.

"Prince Zuko."

Zuko picked up his tsungi horn, then put it down.

Of course it was useless.  He was good at it.
