Lorikeet: or falling and getting a black eye when you are teaching "purple." I've done both, but I've been teaching a long time. Heh heh
My response: ha ha, yeah, I'm not that dedicated!
But similarly, we talked in class about how the spelling of awkward is awkward. I suppose you could have done embarrassing and purple on the same day.
Stuff that I forget all the time even though it's basic grammar, verb forms
drunk
drank
drunken
Most of the useages feel awkward to Americans, and so commonly we use whatever we feel like saying at the momment. That doesn't fly with EFL, so at times I feel silly looking up in to space..."yeah, drunk...that's right- there's no dranken, I know that" duh
