We found a new thing to do while driving somewhere together. We make up stories by building on what one of us has said. Here is an example of the one that we made up on the way to IKEA (our house could easily be in IKEA catalog as just about everything came from IKEA).
Me: Once upon a time…
Anna: There was a frog. It was green and small, loved water and grew from a tadpole.
Me (hopefully): It was a magical frog!
Anna: It turned into a bat and flew in the middle of the night over the water.
Me: And on its way it met a beautiful princess.
Anna: And he bit her hair and scratched her face, and the princess ran away crying.
Me: The bat sat down on the ground, turned back into a frog and said, “I am so sorry!”
Anna: But it was too late! The princess was already too far away. But a beautiful prince came on his horse. The frog turned into a beautiful girl, and they kissed and got married and lived happily ever after. The end.
