Twenty years of schooling...
I've been teaching full-time since 1973, and I do have the requisite 20 years of schooling. And, after all, Bob Dylan wrote (in Subterranean Homesick Blues)
"Twenty years of schoolin'
And they put you on the day shift..."
Well, this semester, I teach until 7 PM two nights a week and until 10 PM one.
I'm still waiting for the day shift.
(This is a whine. You may return to your regularly scheduled activities now.)
