There's a boy in the class, Sam, who's become the one everyone picks on. It's hard to say how it started. Now it's just a habit — people roll their eyes when he speaks, blame him when things go wrong, make him the punchline. None of it is dramatic enough to call bullying, exactly. It's a hundred small things that add up. Most kids aren't cruel to Sam on purpose. They've just absorbed the idea that he's the one you're allowed to be a bit unkind to. A new kid joining the class would pick it up within a day, without anyone ever explaining it.
