Meredith : (opening voiceover) I had this memory game when I was a kid. A bunch of cards, face down, in rows. Each card has a picture. You turn one over, look at it, then turn it back over. Then you have to try and remember where it's matching card was. Sometimes you have no idea, and other times it shows us exactly what we need to see. The cards seem completely out of order and random, but you keep turning them over. And the more cards you see, you get a sense of how everything fits together.
