Bull fighting

The scene of the bull festival really grabbed my interest. I only know the things seen on tv and movies about bull fighting. I had no idea the steers were used for "bait" to calm down the wild bulls. I also had no idea people made such a sport of it. After reading it, I immediately Youtubed some videos to deepen my understanding (as shown above).

I am also wondering if the bull fighting stood as a metaphor of some kind to the situation happening amongst the characters. Any ideas?
