Accused a friend of something

This happened when I was 8 or something. I had this friend who would always follow me around and would never leave me alone. One day we were sitting on a balcony (not very high above ground) and daring each other to jump off it. I jumper and hit my head hard on the concrete. Coincidently, my friend tapped me on the shoulder right when I jumped so everyone accused him of pushing me. I was kinda angry at him so I didn't say anything and let the teachers and every kid in my school rip him a new one.
