As a teacher, it is so easy to be humiliated in front of your class. My worst fear is being caught off guard by a question that I won't know the answer for.
This happens to me every, single day.
"You're not prepared enough. You're a terrible teacher. They think you're a farce. They don't trust your answers anymore. They're wasting their money. You can't even speak English yourself"
I am attacked ruthlessly during those moments of uncertainty. Instead of admitting my faults, however, I get angry and defensive. I have often found myself being adamant about a certain part of grammar, telling a student such-and-such, only to have them call me out on an obvious technicality. Once more, instead of admitting my ignorance, I back-pedal, and pretty soon I find myself angry on all levels-angry at the student for asking, and angry at myself for a.) being prideful and b.) not knowing the answer. It's an uncomfortable situation for both parties, and my first instinct is to run from the room and hide.
I struggle with my own knowledge base. There are even things in the Bible that I know to be true, but doubt my answer if called upon. My mind likes to make up answers to things just to save face. My pride is the biggest obstacle to overcoming humiliation and uncertainty.
Only by the grace of God will I learn how to be more humble.
