Why do countries have borders?
Invisible Lines
Why do countries have borders?

Look at a map and you'll see lines everywhere — squiggly ones following rivers, straight ones slicing through deserts, dotted ones nobody quite agrees on. These are borders, the invisible fences between countries. But why do we draw them at all?
Imagine your bedroom is a country. Inside, you decide the rules: shoes off, no little brothers allowed, lights out at ten. Your sister's room next door has different rules: shoes on, door always open, stay up reading till midnight. The hallway between your rooms is the border — the spot where one set of rules stops and another begins.
