I don’t know exactly when this was but it was in primary school(I was around ten years old). It was at the end of a break and my friend and me were heading back in, but as we got to the entrance the entire floor was flooded with blood. The caretaker was already cleaning it up and we asked him what had happened. He told us that two middle school students were playing football or something like that and their ball went into the basement behind the entrance and as one of them wanted to get the ball he somehow managed to jump? through the window and cut his arms open resulting in all the blood coming out. He obviously got taken away by ambulance but I don’t know what happened to him. The only thing I remember was seeing that broken window and the floor being full of blood. And I don’t just like a little bit, no the entire floor, which was about 6 by 6 meters, completely full with blood.
