I graduated in 2024. I have been in the exact classroom described by the greentext countless times. It wasn’t every single class but it was many of them. All those NPCs/zombies you describe are people in the same boat as greentext. Everyone is wondering when someone else will step up to dip their toe in the water. The moment is fleeting though because soon all the phones are out and people are texting their friends, oblivious to the horror around them.
