It is so much easier to fit four balls in your mouth when one of them is a whole lot smaller than the others...I caught Harley cheating this afternoon. But, I can hardly blame her because sometimes it is necessary to try to fit more into the same size hole. ***Note: Original Content heavily edited here to protect my youngest child from the wrath of one particular Honors English teacher--this post made a whole lot more sense earlier. I promise*** All I can say is I wonder if Hemmingway would have written 'Old Man and the Sea' if he knew what torturous interpretations would be twisted and bent out of this great tale? ...Thank goodness Harley doesn't test us on the direction we throw the ball. She is open to all tennis ball interpretations.
