Kaia has developed a secret language. It's called Sarah, spelled, according to Kaia: Saraey.
Here is a sample of Saraey:
Shee-ow ee Shee-ill shill Shee-aahhh she-ahd-oh. de-oh.
Right now (it changes every time), this translates to:
I'm walking on the sidewalk. I'm going home. I love you.
Saraey has a lot of "sh" and vowel sounds. She'll sing whole songs in it, and have whole conversations with her horses and dolls. Sarah, spelled Sarah, also is her granny's name!
