"I Anna!"

We never know what silly thing Anna will do or say everyday, but it's always something.  Her new thing is that when she does/says something, Joel or I will usually say to her "You are so silly" or "you are so goofy", and she replies back with "I not goofy, I Anna!"  The other day, she was acting like a baby and had a pacifier in her mouth and I said to her "Oh, are you a baby?" and she says "I not baby, I Anna!"
