Three friends, Prisca, Elisa and Rosalba, refuse to accept it. Over the school year they record her injustices, find allies among classmates and adults, and use cleverness and mischief to bring her favouritism into view and challenge it.
When a biased person holds an official evaluative role, like a teacher's power to grade, seat and discipline, their prejudice comes out as neutral-looking judgments such as 'untidy', 'lazy' or 'badly behaved'. Victims who lack standing, such as poor children, are disbelieved because the institution presumes its agent is fair. So bias does its greatest damage where it has been converted into official assessment.
A teacher who favours some pupils does more than hurt the disfavoured ones. The whole room learns who deserves respect: the favoured learn entitlement, the humiliated learn shame, and the onlookers learn that staying silent is safe. Seen this way, unequal treatment is a hidden curriculum. It reproduces social hierarchy through everyday classroom rituals, not through any explicit lesson.
People who cannot win a direct confrontation with authority can still shift the balance. They coordinate, document specific incidents, and bring them to adults or institutions who do have standing. A single child's complaint is easy to dismiss, but a shared, consistent record from many witnesses is not. Solidarity among the weak, including privileged peers who refuse the favour they are offered, is what turns private grievance into public accountability.
