So, running of the bulls is a big event that happens in Spain. People dress in white clothes and red bandannas and run through the streets with bulls running behind them.
But why do they do this? Well, it's a tradition that started a very long time ago. People used to move bulls from one place to another, and some people would run in front of them to make sure they were going the right way. Over time, this turned into a big festival where people would gather and run with the bulls just for fun.
Nowadays, people come from all over the world to participate in the running of the bulls. It's really exciting, but also very dangerous. The bulls are big and strong, and they can hurt people if they get too close. That's why it's important to be very careful and stay out of harm's way.
So, some people love the thrill of running with the bulls, while others prefer to watch from a safe distance. But either way, it's something that has been a part of Spanish culture for a long time, and it's a really big deal for a lot of people.
