Wayfaring Stranger - I enjoy Neko Case's version, but whichever you like.
"Toph! Sokka! Come in and have a seat! I will be with you in one moment!" Iroh's voice boomed across the teashop when he spotted the pair standing by the door. Everyone in the shop turned to stare at them, these two heroes of the war. Iroh's teahouse was one of the most popular teashops in Ba Sing Se, and many patrons came in the hopes of spotting a celebrity there, though they returned again and again for the delicious tea.
Toph quickly scooted over to an empty table by the wall, and Sokka followed her gratefully. He wasn't used to being stared at by so many people; usually he was beside Aang when so many faces were turned towards him. Maybe Toph didn't have such troubles because she couldn't see them. Sokka envied her her blindness.
"I wonder if I had been born blind, if I would have been as awesome as you," Sokka wondered out loud, as he sat down across from her.
Toph turned her face towards him and smiled. Sometimes when she looked right at him, it seemed like she was really seeing him; her eyes were so clear sometimes.
"If you had been born blind Sokka, you would just be even more of a klutz than you are now," she told him.
Sokka nodded. She was probably right. He didn't have any bending skills to help him.
Iroh joined them in a moment with a tray of tea. He set the pot in the middle of the table and handed out three jade coloured cups. "Ginseng tea," he said as he poured the tea out. "Truly, one of life's finest pleasures."
Toph picked up her cup and took a whiff before sipping. "I still say oolong is best," she said.
"It's not your fault you cannot understand the full beauty of ginseng," Iroh replied. "You have much to learn still."
"I don't know how understanding tea will change my taste buds," Toph countered. Sokka glanced between the pair; it seemed like an old argument, and he wondered how often they met.
"It is good to see you again," Iroh said, smiling at Toph, and then turning to Sokka. "You are far from home; what brings you to Ba Sing Se?"
Sokka shrugged. "I just wanted to travel again," he explained. "It's hard to stay in one place once you've seen what the world has to offer."
Iroh nodded. "True. Very true. It sounds like you are full of wisdom for your age. Much unlike this young one," he said, jabbing his thumb at Toph.
Toph snorted. "You think Sokka has more wisdom than me? I don't think I've ever been so insulted in my life!"
Iroh sighed and shook his head. "I try to teach her how to live in harmony with the world, both inner and outer, but she is as stubborn as the earth she bends."
Toph smiled, as though that was a compliment. Sokka smiled too, seeing that he had a kindred spirit in Iroh.
