Like the world of adults, the world of children does not tolerate differences that distinguish someone against the background of others, which are considered "normal". This world is cruel, because its inhabitants, unlike the inhabitants of the adult world, have not yet managed to learn to hide vile thoughts behind a fake smile. Many things are incomprehensible to them, moreover, they are not known. The children are straightforward. And that's why they are very cruel. However, all children ever grow up. And looking back, in times of school routine, some of them feel ashamed of their youth. It's hard to imagine how many years must pass before a rough asshole and slobber comes to him, what a fool he was when he mocked for fun disabled. Someone will not even remember it. And someone like Shoi will hate himself with strong hatred. In junior school, he managed to turn the life of a classmate named Shoko into hell. Just because she was deaf, not like everyone else. And now, a few years later, though belatedly, the boy realized that to say something important to someone who can not hear you does not necessarily use a voice.
