What about learning? Did you ever think that playing football was dumb or that science class is dull or that all cats are worthless? But what happened when you made the football team? It probably became a lot more interesting. And what about that science teacher who let your class loose in the back field to shoot off homemade rockets? Perhaps your opinion changed. And cats? Well, some people will never change their opinion about cats. But I know of someone who insisted he hated all animals, but was recently sighted patting a kitten who had curled up on his shoulder and was purring loudly. It was through experience with these different ideas that people changed their minds.
