I got Caroline in her full-on ballet recital getup for a rehearsal at her dance school, and she was practicing in the mirror while getting into character as a dancing dog.
She demonstrated how the arms go up and how the hands are to rest, just so, and she said, "Our fingers are not supposed to touch over our head. I remember that because those words were in a warm-up song one day in class a long time ago."
I was impressed that she remembered something like that and paid close enough attention to catch it in the first place.
I said, "Wow, that's right. Your fingers are not supposed to touch. How do you remember this stuff?"
And she said, "Well, I remember everything. Why do you think my head is so big?"
