I've been finding that I say that statement a lot these days. Molly is a quick little whipper snapper. My favorite recent story regarding this took place on our drive back from Tahoe. I was driving and N was in the passenger seat. It's dark out and Molly asks daddy for a book (part of a 4 book Disney Princess set from Costco with its own carrying case). She specifically requests Ariel (The Little Mermaid). N reaches into the backseat to find the case on the floor. He then mutters that it's too dark to see what each book is. I tell him to make sure he gives her the right one and his response is, "How is she going to know?"
N hands her the (correct) book. I glance in the rear view mirror and see Molly calmly holding the book up while waiting patiently for us to pass under a light or for a car to pass us so she can verify she was given the correct book. Once she gets enough light to confirm she is indeed holding the Ariel book she puts it back in her lap and proceeds to thumb through it.
Like I said, "She's not dumb."
