ESL Grammar Teacher
This sounds odd, but I teach grammar. I have been an ESL teacher for the last 7 years and a HUGE part of that is grammar. In class I can do everything ok, and explain the different between an adjective and a past participle.
But you take me out of the classroom and all of a sudden, I can't speak English good no more. I make up words like hippototamus, and elelelphunt. Instead of asking which number bus we need, I'll ask which flavor bus we need....At first people are weirded out....but eventually they learn to understand it and while they never learn to speak it, can at least interact with me appropriate to what my topic is.
