Toph: Look here Sugar Queen, I gave up everything I had so that I could teach Aang earthbending, so don't you talk to me about being selfish.
Katara: Sugar Queen? (Toph uses Earthbending to slam the door) Did you just slam the door in my face? How can you be so infuriating? (Circling tent in a comical fashion)
