You teach pre-teens, and they do what you tell them too? They are unlike any pre-teens I ever knew or heard of...
So do the teens I teach.
Unfortunately teachers in this country depise the kids they teach, and show it.
I just treat the kids I teach as if they are my equals (which some of them are; most
are way ahead of me) and very quickly a feeling of mutual respect develops.
Also, if some kids mess around and they look at me expecting a reaction they get one, "I don't care, my English/Programming is
far better than yours, so if you want to piss around it's your loss not mine."
