Monthly Performance Evaluation

The uncle was always very kind and lenient with his young niece, except in one case: her school performance.
Every first Saturday morning of the month, the online gradebook was meticulously examined, every good grade rewarded, and every bad grade severely punished. But it wasn’t the punishment Giulia feared the most; it was the time leading up to it: she had to sit, completely naked, next to her uncle, holding the long stick with which she would be punished.
