Freeze game
When we're driving, especially through town, Savannah has a game she created her self. It's called the Freeze game. When she says someone's name in the van, usually, Mama, that person must stop talking (or singing). Only when Savannah sees the letter M, or the letter G for Georgia, can I start talking again. Then it's my turn, I say, "Savannah," and she has to stop talking.
If she catches me talking she says, "Quiet, you." Just in case you're wondering, this is not an expression she got from us. She has picked up a few expressions like that.
