One of my Top 5 too. Three others that were great. Can't remember the titles.
Burgess Meredith, worked at a bank, and all he wanted to do was read books. Was in the vault at lunch, nuke strike. He is sole survivor. Goes to libray, gets a stack of books. Breaks his glasses on the steps. Phecked.
Guy with bomb shelter. Air raid warning. Goes into shelter with his family. Won't let his neighbors in. Turns out to be false alarm. Phecked.
Girl dreaming about Earth spinning into the Sun cooking the Earth. When in reality the Earth was freezing due to it leaving orbit, and heading into deep space. ( I may have it backwards). Really phecked.
Great stuff.
