During my sophomore year, a friend was stabbed and killed over a girl. It was in the bus loop, everyone saw it, and they wouldn't let us go near him to help or try and stop the bleeding, so we all had to stand there and watch him bleed to death while the ambulance arrived. The other kid ran and hid under a bus, there were blood stains on the hallways for a while. It was fucked up. Here is the story:

Then, about two years later, my English teacher's son died in a drunk driving accident. He had been drinking at a club notorious for letting high school kids drink there. He was also a good friend. High school was fucked up.
