Teachers, at least teachers in the US anyway, should get paid a lot more than they do. The crap they endure is almost on par with that of cops or prison guards, with the added risk of ignorant and unruly parents or the kids just making shit up about them that can ruin their lives, true or not. I respect the hell out of anyone with the patience to run four or five classes a day and not finish Friday afternoon by picking the worst one of them up by the ankles and using that one to beat the shit out of the rest of them. You're a teacher? You're a badass. Let no one say otherwise.

As for the students, I suggest a change in some classroom rules or possibly some phone calls home. Depends on what you're dealing with. Also, to look on the bright side, it's halfway to March, which means only 4 1/2 months left of them! Hopefully next year will be better? Best of luck, OP.
