9/11 means a lot of different things to a lot of different people almost twenty years later. I don’t want to dwell too much on the obvious, but I will say for me it changed how I look at America. Like most American’s my age, we’d never felt vulnerable to an outside attack like that. Maybe drills in school to duck and cover if there was a nuclear war, but I never thought anyone was crazy enough to push the button back then. That morning was the first time I’d ever thought someone from far away had figured out a way to hurt America at home. It made the tiny blue dot we live on together feel just a bit smaller, too.
