One morning at school, you were walking down the corridor with your backpack on your back. As you walk, you see a crowd of students from a distance, many cheering and some of them taking videos with their cell phones. Then because you were curious, you walked through the crowd and tiptoed trying to see what was going on. And you raised your eyebrows in surprise when you saw two students fighting and fist fighting with each other, even their faces looked full of wounds and bleeding.
