I Just Don't Get It!!!

Riley spends alot of time each day looking through books on his own. There is one particular book, "My Two Hands, My Two Feet" that frustrates him. He will begin flipping through the book and half way through it, the story starts over from the other side (upside down). All of his other books have stories that begin and end in the same direction. Sometimes he will get so frustrated at the book that he'll toss it aside. It is so funny to watch.
