Only interesting because as soon as I read the question I was transported, suddenly a little girl staring at helicopters and buildings on TV and a crowd. I couldn't quite understand what it was about, just that it was Viet Nam because that's what my brother said. It was only years later, in history classes, that I realized what I had seen was the fall of Saigon.
The more interesting incident was the second time I remember something in history- about a year later. Larry Flynt was in trouble with the law in Cincinnati (the world's most repressed city.) In order to show his magazine was not pornography, he sent a publication of what he considered obscene to anyone who might be connected to the case. That included my family, so we got a copy of it in a plain brown sleeve. I always got the mail because at six it's like the world's most exciting job- so I looked at the mailer since we'd never had anything arrive in a plain brown wrapper like that. It was the first time I'd ever seen pictures of mangled bodies and other war atrocities. Mom had a hard time with that- much more so than me, I think. Years later when People vs Larry Flynt came out, I didn't go see it. I might be utterly behind the first amendment, but Flynt was (and will always be) a jerk.
