I remember in 2011 my girlfriend was taking a creative writing class at community college and the teacher had a no 9/11 plot twist stories. Apparently kids were writing mundane uninspired slop about families eating breakfast and having a normal morning and then one of them would go yet clapped in 9/11 and it would be a sad plot twist reveal at the last second

“…and then after a breakfast he got on the plane and took off. The day? 9/11/2001. The flight? United 93… The end.”
