Maddie is a what?!?

We were visiting with our neighbors, Maddie and Tori, the other day and the moms were talking about how good Maddie is in the bathtub. She loves being in water, it's fine with her when you rinse her hair, she loves swimming lessons. I exclaimed: "Maddie is such a little fish!" Anna stopped eating, and looked up at me with HUGE, nearly-panicked eyes, and asked "Maddie is a fish?" As if she had been betrayed all these months and is just finding out that her sweet little friend is hiding fins beneath her clothes.
