I asked my dad once if his high school teachers began treating kids differently during Vietnam, when they knew some of their students would be drafted and sent to war. I was curious because for sure we’d started treating our military kids differently after 9/11. He just shrugged and changed the subject, like he always did. And that was okay with me. He’d go back and change a lot of things if he could; and like everyone else, I’d give anything to go back to the day before 9/11—but all we can do is move forward.
