Public school officials went wrong, that's what. No personal responsibility combined with sadistic cruelty and indifference, controlled by the most fascistic arm of liberal politics.
What could possibly go wrong?
It’s the same reason hotels over book. A certain percentage of people are expected to not show up. And sometimes that group lets down the side and actually shows up. It’s unfortunate, and they probably should have figured out some sort of “over flow” plan, but it happens, probably every single year at multiple schools without it hitting the news.
