Violet kneels on the floor holding a football upright with her finger. In a panic, she exclaims,"He'll kick my hand! I just know he will!"
As Charlie Brown runs up to kick the ball, she let's it go saying,"I can't go through with it!"

Violet stands over a dazed and pained Charlie Brown asking,"You didn't kick the ball, Charlie Brown...why didn't you kick it?"
