Snow White & Grumpy

So Sienna was on the horse sitting with both legs to one side, "like princesses sit on horses." I hear her say, "I'm gonna be Snow White and Rywie you can be Grumpy."
Me: "Why is she Grumpy?"
Sienna: "Because she is always grumpy and crying."

And as most of you know that's true. She throws huge tantrums quite often.
