Turn on the magic.
I thought that I had a solid grasp of discourse analysis, I really did. I've never received a mark lower than an A+ on any of the discourse analyses that I've written over the years, however. Doing a presentation on the methodology and theory behind it was absolute torture. I had a mental breakdown, which triggered a mental regression that led me to play Litebrite, cry and admit that I know nothing about critical linguistics . (okay, that last part is hyperbole, I just got sidetracked by nerves).
One person said that they really liked my presentation, but it didn't matter. He has skipped, what essentially amounts to, the entire school year, so he never saw any of the good presentations. Even the bad ones were better than mine.
