Downtown

Every town, regardless of its size has a downtown. But one town has an uptown, New York City. This makes things a little unclear for me. My guess would be that "downtown" was a term that originated in New York city to differentiate between North and South Manhattan, hence uptown, (North) or downtown (South). But in every other city downtown refers to the commercial section of town. I know this would make no sense in Manhattan, but why call it Manhattan then, why not call it the same thing we call every other part of town that's commercial? Why don't we call it Downtown New York? Or maybe we should stop referring to the commercial areas that are in the north part of their towns, or in the middle, or even if they're in the south part, as downtown and just call refer to it according to its actual geographical location, like Manhattan does. Of course, regardless of the semantic illogic, everyone seems to understand the system. No one seems to see the outright untruth of calling the North part of town downtown, just because it's commercial. We know that people mean the commercial part of town when they say downtown. We need not be too picky about words. On second thoughts, I think maybe we should reconsider our thoughts about being "too picky about words". On third thought, maybe we shouldn't be too lax with words, neither should we be too picky. We should be just right, like everything baby bear owns. Because upon further thought, North isn't technically up, and South isn't technically down.
I am going to make a map with Antarctica on the top. (But what shall we make of east and west?)Hmmm... And who decided that the middle of the Pacific Ocean was where a day would change?
