Borders

Why does the world have borders?

Is it like the lions in their grassy savanah, where territory is regularly marked and a breach of those lines by another of the same species is a direct challenge?

Is it linked to the reasons we lock our doors at night, a need to reassure ourselves that all we have worked to own, worked to build, worked to be is safe from prying hands?

Or maybe it's the resounding effects of the feudal system, where the common populace fled to their lord's keep in case of attack. Maybe the separation from fief to fief became so much more; maybe someone drew the distinction between each fief on a map and they got changed into borders.

Is it a result of man's want of control? Maybe one person wanted to run his little world a certian way, and a different person disagreed. If the first man just went off into his own country and did as he pleased, the other person should leave him alone, right?

Even in my own life, I get angered if people encroach upon my room- think of it as my country, as my little brother and sister pretend it is when we play Legos. If the ruler of LegoLand (Steven, lol, we actually DO call it that...) breaches my border (my room) without my explicit permission, I usually drag him out or scare him away (I can be very scary, you know...). It's MY place, my private space to be alone, to think, to dream.

Seems that borders are the best way for an untrusting society to find some semblance of comfort, a sense of a (maybe?) false security. Or maybe just to find some peace and quiet from the rest of the world.
I leave the judgement up to you- as far as I can see, borders work pretty darn well at the moment...
