I understand, V. I REALLY do.
Not to add to your insanity, but just so you understand: I have a group of kids this year that literally make me hate going to work (and I've never hated teaching). Lucky for me (insert extreme sarcasm) I get to teach all 104 5th graders. A good 30 of them make my life hell everyday. I take so much time dealing with discipline and teaching right from wrong and catching them being sneaky, that the other 70 don't get what they need. It's like teaching preschoolers.
All day I say things like: Johnny, don't touch that. Sam, take your pencil out of your ear. Joey, you've been working on that paper for 30 min. and only have one problem done. Bob, stop licking your arm and the desk. The minute my mouth shuts- theirs immediately open and are talking non-stop. It spreads like wildfire. It's insane. The word fa@@ot is all over the place. Really, I'm ready to leave teaching. In the 11 years I've been doing it- it's gotten worse and worse. I fear for the future. I just know I can't handle dealing with it every day.
Now, on the other side- the other 70 I have are wonderful. I wish I could tape the mouths shut and tape the 30 to their chairs so I could have some meaningful learning time with the ones who really want to learn. I'd go to prison if I did that, but for one day it might be worth it....
And don't get me started on the parents I have to deal with, too. I've just accepted that it's always my fault this year, it's not their kid, I'm to blame for their 11 years of bad child rearing and I'm just picking on their kid.

Now it's off to work to go play policeman, counselor, judge, jury, mother, dictator...
