Well. Microteaching could have gone a lot better. It could have gone a lot worse, too, so let's call the scales balanced. I think I may have pysched myself out a little too much, because once I was up in front of the class I seemed to be all right. But time (and my peers) will tell.
Also, next time, bring cough drops instead of a water bottle. You can't spill cough drops on you.
