in 4th grade the teacher didn't do anything about it, one time my 4th grade teacher got up and left the class and I got into a big fight, I got beat and suspended for 1 week and the bully got suspended for 3 days, luckily my parents knew what happened so they got mad at the school, and didn't punish me.
I am lucky to have had school in the 1990's because if this was earlier in time the school principal would have beaten me, because no matter who I told, at school nobody believed me. Or the teachers didn't want to acknowledge it
my parents saw all the bruises, and there was proof of neglect and abuse, but the school didn't do anything, and as for the cyber bullying? yea I tried to take my own life, because of that, I could not even play a video game without it crashing, or the CD being overwritten and corrupted, the people that were doing this stayed hidden and once again nobody believed me until years later when I was able to get proper connections in my community.
