When I was somewhere between 7 and 10 we had to read a book about the atomic bombs dropped on Japan (this was in the 80s, not the 50s). The book was written from the perspective of the Japanese, and we were suppossed to be learning not to be ethnocentric (which is great). However, somehow it escaped me that my own country had dropped the bomb (maybe I'd have been more scared if I'd known we did something like that). I also didn't get it that atomic bombs hadn't been used since WWII. For weeks I'd stare at the ceiling of my bedroom waiting for a bomb to fall through and nuke me.
