While I was watching the series for the third time, the part that intrieged me the most was: Why don't people in the fire nation dance anymore?
I understand that due to the seriousness of war and it being a war nation, but they play music, have plays, do comedy. They have fun in other ways so why not have fun in an exercise that will help maintain and get good physical condition.
Even Zuko shows how dancing is better by getting better at fire bending once he learned the "Dacing Dragon"!
Thir ancestors danced and were actually GOOD people not the monsters they are today!
