"What did he say?" Didn't you hear him? He spoke in words. You have ears. You know sound when you hear it. You have a brain which can decode sounds for you. You can understand how things work. You can correllate a sentence with the objects it's talking about. And that's why you can never say that you didn't understand what he said.
You know you heard him with your ears.
"What just happened?" Didn't you see? Things moved in front of your field of vision. They didn't happen when you had misplaced your glasses or anything like that. Wait a minute, you don't even need glasses. You have perfect vision. (You only ever wore glasses when you wanted to pretend like you were some sort of intellectual. You wanted glasses to make yourself look as if you had a life.) You can see things happen in front of you. That's why you've been given eyes. To see. And the stuff whose light entered your eye had a direct connection to your brain. Your brain can decode optical information into mental pictures. You can use these mental pictures to perceive the stuff your eye saw. And that's why you don't ever need to complain that you didn't know what just happened.
You know you saw it with your eyes.
You have seen life for so long that by now, you know how things behave. This is great for you. Because you know how things work and function, you can interact with them and make them do things for your benefit. Superman knew the air. He knew his body. He knew that a cape flying in his wake makes for a powerful image of purposeful flight. So he used it all to make himself fly, and earn millions of dollars for selling himself as a potent image of an alpha male. Not that you can fly. But you can see. And that's all you ever need to do. And it's all you can do. That doesn't have to sound like an escapist thing. It's only as escapist as a horse-rider saying that it's upto his horse to do the galloping. Provided he has fed it. Provided he has made sure that the bran in its bowl was not mixed with anything the horse was allergic to. Provided he has made sure she gets enough exercise and sleep. The rest happens as part of a mechanism. You can't say no to the mechanism. It's like air to your lungs. Breathe it in. You're sure to come back for more.
