This was written during a time when I still took it personally when my students asked me if I minded if they blew off my lesson and left early. Now I’m not bothered as much. After all, I’m only a teacher, not a real human being with feelings.
You have some time today, I see.
Your teacher’s canceled Chemistry.
My class won’t start till three-thirty.
And would it be okay with me,
Since there’s some place you’d rather be,
You ask, I hope, facetiously,
Whether I would mind terribly,
If you skipped my class and left early.
I try not to take it personally,
But it’s very plain for me to see,
You don’t care about the class or me,
But I know you want me to agree,
And so I do, but quite sadly.
Random Misanthrope 
Well done, though I hope you don’t agree quite so readily anymore. 😉
Hehe…nope. Usually they say, “I don’t like you, anymore!” To which I reply, “Good. You’re not supposed to like me. I’m your teacher.”
That, is an excellent response!
I’d say something along the lines of “It doesn’t make any difference to me if you’re here or not. If you can learn the material well enough to pass your exams on your own, have fun. It’s up to you.”
But, I don’t like people.
That’s pretty much how I feel about it, Dock.
Most of the students who couldn’t be bothered to occupy themselves for an hour and a half, and would rather piss off, are the arrogant snots who do think they could prepare themselves for their exams without any help. Good luck to them, I say. I have plenty of dedicated students who need my help.
And out the door goes their degree.
