Most teachers are teachers because they enjoy teaching. If you don't, retire if you've got enough time in , or find something else before you do harm. Teaching is too sensitive of a position to do otherwise. I was lucky, I had several wonderful teachers growing up, only one that should have been retired.
Poor teachers get me wound up. Bulrush, I hope you realize that none of my rage was directed at you, nor anyone else here. I have been a Big Brother and am a mentoring type myself though, so I am pretty passionate about teaching in all the ways it can be done.
I have now been three weeks without a cigarette, maybe that had an effect on my temper too.(I don't think so, but the possibility exists.)
