Work Text:
Ty Lee is good at smiling.
There are plenty of muscles in the face which can be exercised like any other part of the body. Smiling’s just another part of her acrobatics training.
She learned early on that if she pretends to be a cheerful airhead – just a silly girl – then people underestimate her. They get caught off-guard and she gets the upper hand.
It's saved her plenty of times.
But, to be honest, she prefers genuine smiles instead. The ones when she's spending time with old friends, like Mai, and new friends, like Suki.
With them, she can relax.
