They told me they were going to beat me up. It was not during a break. The teacher who should have held that class was sick or something and the school messed up organizing a replacement. When no teacher showed up, most of us just went back out into the school yard. I was alone at the playground, which was furthest from the school building. Those three kids came towards me in a triangular formation and just told me they were going to beat me up. I preemptively kicked the front kid as hard as I could and the other two ran off. I left the kid lying there and went back to the class room. One of them actually reported me to a teacher. Somebody from the school talked to my parents and told them that I reacted very violently to a situation but that they thought the other kids provoked it (at least one of them was a known trouble maker). I had an awkward conversation with my parents several days later that violence is not OK even if the other people are in the wrong blah blah. I never got into any real trouble over it.
