Have you ever noticed how you can't necessarily do anything you want, but you can thinkanything you want?! For example, say you really want to fly like a bird, but without a plane or a helicopter. You can't exatly DO that, but you can THINK that! Or, say you really don't like somebody, and you think people will get mad at you if you say it. You can't really say that, but you can think it as much as you want!
