My teacher locked the door, had a breakdown, and told us we were all gonna get blown up by incoming missiles. Told us to get under the desks and not trust any other adults.
Eventually some school admin came by and calmed her down. She went on leave for about six months and when she came back she had gained a bunch of weight and had to always hold a crucifix or else she got anxious.
I grew up in the south, thousands of miles away from NYC
