(Speaking about ponies engaging in a game of running around and chasing a ball with "imaginary riders") Along with everything else about it, it seemed to be a parable for life. Going forwards and backwards and round in circles, striving ever forward only to have to run like crazy backwards to get the ball again, realizing that your enemy is after the same goal and you're actually helping him toward it and getting roughed up and possibly killed while you're at it but still feeling the comradeship of being in the game all together.
