So, I have rather long hair. And I tried to braid it straight down my own back. This was a failure, as I found that I could only get to about my shoulders before I had to have someone else finish it for me, and I wondered how Ty Lee would get that waist-length braid of hers done.
The answer, of course, is that she's a cartoon character.
But that wasn't sufficiently Ty Lee, so I came up with this.
"Ty Lee."
Ty Lee glanced up from her hair. "Oh, hi, Mika," she greeted her sister. "Is breakfast ready yet?"
"Yes…What are you doing?"
Ty Lee shrugged, a normal action made strange by the fact that she was hanging upside down by her knees from the railing. "Braiding my hair."
"I could braid it for you," Mika offered.
Ty Lee smiled. "I like it best when I do it myself. It's not tight enough when anyone else does it."
"But…why do you do it hanging upside down?"
"Well, I can only get so far down my back without doing something."
