Do You Know?

Did you know, I didn't. Know what, what should I know. Do I care, yes, no, maybe. What should I find out, know what. What to know, what to learn. Learn what, learn to know. Know to teach. Should I teach, do I know, do I not know. What do I need to know to teach, or to learn. Do I need to teach to learn, and not learn to teach... Do any of you have any idea of what I'm talking about.
