Equilibrium: At the beginning of the clip we can see that the man is spending almost all his time with the horse. From eating to sleeping to playing, and even driving while the horse runs makes them both happy.
Disruption: The Budweiser truck appears and the horse is then taken because he is needed to be a part of the parade. This ruins the equilibrium because the man got his companion taken away after we were shown that they do almost everything together.
New Equilibrium: After the horse's services are no longer needed, we can see that the man and the horse are reunited once again and the equilibrium is once again restored.
