Kind of a funny story:
In 5th grade, at lunchtime, we had the option to go on our handheld devices and play games. Now, in 5th grade, for my case anyway, Minecraft was probably the most popular subject amongst the students. As such, my friends and I would play Minecraft: Pocket Edition with each other during this time. Unfortunately, this also led to cyberbullying... Sort of. I was unfortunate enough to be in the same class as four Neandrathals. This usually led to griefing, and, although it's not that big of a deal now, as it is just a game, it was aggravating back then. These kids also insulted our families and such. I'm not talking about playground "Your Mama" insults either. They made our lunch, and usually the rest of the days miserable, and it was the one reason why I disliked 5th grade. It wasn't easy dealing with them mainly because one of them was actually my "friend" until he left me, therefore giving them access to personal background information that I wish I hadn't given out. This "friend" did the same thing to another kid, who, funny enough, ended up becoming my best friend (until the middle of the next year, when he moved to a different state), and didn't stab me in the back like the other kid.
Anyway, one day, we were playing MCPE, as usual, and these kids started insulting my family, particularly my mother. I didn't fight them or anything, but I did impulsively send a very profane message in the Minecraft chat. These kids then told the principal, and I got in trouble for it. I'm not sure why, though. They were the ones who set me off, and I even had the decency to censor the bad parts of my message.
My folks sent an email, I had to go talk to the principal, I had to apologize, blah blah blah.
I still don't regret sending that message, even though, in reality, it didn't do much.
