That's a bit of an exaggeration, don't ya think? I don't think I've ever met anyone older than 5 who didn't know where their state was.
Yeah, I suppose I'm exaggerating. My point is that there are a lot of things you would assume everyone knows, but a lot of people don't. Most people couldn't point to all 50 states, or point to Germany on a map of Europe, or tell you what year World War II ended.
Or maybe most can, and I'm just surrounded by the wrong people lol.
