AAHAHahahaAHAh!! I just taught such a bad lesson. A load of sadness has descended on me. I didn't prepare enough to teach a "grammar tense review" and that makes me insecure coming into the class. Cuz then I'm afraid they're going to ask me some really specific question I can't answer. Sandy was telling me before class, "Don't worry about it. I never study the grammar before I go into class. I just figure it out in class." Then we decided it wasn't that I didn't know the grammar it's that I freeze up when they ask me technical questions. So she was giving me tips on how to stall for time while looking for the answer. But I think that just doesn't work for me, it just freaks me out to walk into class and not be sure I can answer any question they throw at me. So my whole class I felt I was hummmming and hawwwwwing, "ummmmm, I don't know why, Byeong-il" and then blushing some more. I think they could all see it. I felt like a shy child up there and I think I've lost their confidence in me. (sigh) And on top of this I've acquired this incredible propensity towards blushing!!!! It's a nightmare!!!!!! For the last six months I've been noticing an accelerating tendency in me to blush beet-red in mildly embarrassing moments, which then succeeds in making me truly embarrassed. And on top of that I told my students about that but then later regretted this because I think that made me blush more.
