My Teachers Day thoughts, though a bit belated:
I'm a teacher. That's my job. But don't expect me bend over backwards and rip my own heart out to help each kid pass their exams when they aren't.
My best teachers were those who taught me nothing. They didn't pretend that their words were gospel or that if I didn't heed them, my life was over. They did share their ideas, but let me form my own thoughts and reach my own conclusions, and we had enjoyable tutorial discussions because of this kind of mutual understanding. They were an interested audience to my exploration of less popular pathways of coursework and were pleased to give me space and independence to bring back my discoveries for evaluation. Though they often graded my work with raised eyebrows, they were fair as well.
For my own part, all I really am is just some dude who picked up a couple of skills over a few decades of experience. All I do is pass them on to those who need them and can make use of them. I entertain no further aspirations nor illusions about this job my mother tells people I have.
