Okay kiddo, have you ever heard of paper street? No? Well, it's not like regular streets that we can walk on or drive on. Paper streets are imaginary streets that are drawn on maps, but they don't actually exist in the real world.
You see, when cities are being planned, they draw up maps with all the streets and buildings they want to build. Sometimes, they draw extra streets that they might want to add later on. These are called paper streets because they only exist on paper.
But why would they draw streets that don't exist? Well, sometimes city planners want to leave space for future roads or buildings, but they're not sure exactly where they'll be built. So they draw the streets on the map as a kind of placeholder, in case they want to use that space later.
Also, sometimes people buy land with streets drawn on the map, but the streets are never actually built. This means that they have land next to imaginary streets that they can't use like a real street. It's like having a pretend road next to your house that you can't drive on or even walk on.
So, that's what paper streets are, kiddo. Imaginary streets drawn on maps that may never come to life in the real world.
