So i [M20] did this to a friend [M probably same age, idk] 11 years ago. For context my school had 2 parts in lunch time, third and middle floor for boys and first for girls. Idk why they did this, but okay.

In that age i was always bullied because of my hair, what was (and is btw) longer than it "needed" to be. So they would always call me "girl", " faggot" and stuff, they usually forced me to stay in girls floor, and bo one did nothing. Even if i was bullied i had "friends", but just to run, like every boy in that school. That "friend" (I will call him "J") J was cool, but still doing bulling with me.

The day was a normal day, like always, bullying and stuff, every single boy running, and there was him, J. He was standing still, doing nothing, right in front of the stairs. So what a normal kid do? Still running like i was doing, and i did, but not just it. For some reason i don't remember why, my brain told me to push him, and so i did. Maybe i thought it would be fun or something, i didn't thought about revenge or this stuff. 5 minutes later, ending of lunch time, his sister run to me, crying because her dad was here. for what? take her brother to the hospital. Next week, he was back, with a broken leg and using crutches. J himself told me that him "fall" from the stairs and broke his legs, the doctor said it was in three parts, i felt SO bad, but i didn't say nothing, never did.

I did not do this for "revenge" or smth, in that age i think i didn't know what it is.

Maybe you ask "and the security cameras? " Here (Brazil) some public schools don't have security camera and stuff. I didn't told anyone about it NEVER and i know the response to the title question, but want to hear it coming from you guys. I didn't use the bullying as a excuse, just for context or smth
