You know, I’ve never figured out what “one mile” means. Despite the culture osmosis, I still stick with the local system for a lot of things. Names of food and local plants, for instance. And measurement. So you can throw me as many “miles” or “inches” or “pounds” as you like and they wouldn’t mean anything to me. I’d stick with my “meters” and “grams,” thank you.
It’s just kind of funny how someone’s saying that they use the term “miles” instead of “light-years” because it’s more layman’s term. Light-years, I can imagine, but
“miles”, I still have no insight at all.
