Let's say there are two theme parks in your city.
One of them is named "Funland" and the other one is called "Freeland".
Now, Funland came first. When you were growing up you loved going to Funland. It had lots and lots of fun rides. In fact it had so many rides you we never able to get around to riding them all because each ride at Funland takes tickets and tickets cost money.
But a few years ago some really big fans of Funland banded together and decided they'd build their own theme park. And they called it "Freeland".
Now the funny thing about Freeland is it has all the same rides as Funland, but with one major exception: they're all completely free! And there is one very, very minor difference. The rides at Freeland are 99% to 99.999% the same as the rides at Funland depending on the ride (some of the less popular rides have a little little difference here and there, nothing you would ever, ever, ever notice once you were actually riding them, like the paint of the ride being sky blue instead of azure).
Now, here is the question, why would a person ever go back to Funland where you have to pay money, when they can just go to Freeland for Free?
