...i'm not perfect people!

they expect me to be perfect the first time around. the teacher who taught it last year. the administration ("oh no, we understand you're still learning..." bullshit). the freakin' students. some colleagues. can i help it that i'm teaching an overload and have little time to plan? can i help it that most things i plan are planned the night before? can i help it that i don't use every trick from every one of my 50 how-to-teach books in every lesson? can i help it that i barely have lessons? can i help it that i thought i made a supersaturated solution of cupric sulfate, but it was really undersaturated (but all the solid wasn't completely dissolved!) and i accidentallly dissolved your lovely seed crystals? can i help it that i'm not as tough as the new first year teachers? i need to quit this profession.
