Nice animation style.
I wasn't bullied at school. I went to a fancy private school that actually took bullying half-seriously. Also, I managed to avoid bullying by basically mimicking wall paper, so that no one would notice me, and it worked - no one did. Nobody hated me, nobody liked me, I was just "some guy" who went to school. Sure, it would have been fun to have been popular, but I settled for not being hated or noticed or bullied.
But I think I can relate how bullying hurts people in ways they don't want to admit. These days, you have adults who say "why is there so much fuss about bullying?", without really understanding that it can be very traumatic for a child. When you're 30 and have a career and a family, when you look back at bullying (even if you experienced it yourself), it seems like a distant thing, something that's not so bad. But of course, the 13 year old or the 10 year old kid being bullied has a very different perspective than an adult. A 10 year old or a 13 year old kid might not have things in their life they can feel good about. They don't have the experience to deal with harassment or bullying, so for them it is much, much worse.
I've seen the effects of bullying. I know one kid who tried to kill himself. It wasn't just the bullying, he had other things going on at home, but the bullying contributed. Luckily he didn't kill himself. I know of people who descended into abusive relationships because bullying made them feel as if they couldn't do any better. I know of people who, to this day, refuse to even be in relationships because of the deep-seated insecurity bullying instilled in their minds.
It's a serious problem. One that adults tend to overlook because either they never experienced it, or because, for most, it has become a distant memory of a different life. But it still hurts the kids who bear the brunt of it.
Unfortunately, what can one do? Kids are idiots, for the most part. They're selfish, and most of them cannot comprehend the gravity of their actions. You can't punish kids in the same way you'd punish adults. What can the authorities do? It's up to parents to stop their kids from bullying, but parents have a natural instinct to defend their children and see their kids in the best light possible.
