Why are...

Teachers so bloody stupid?

I am having a big problem understanding the grammar in Dutch due to the fact it is all arse end up compared to English, if you talk backwards in English the your speaking Dutch.
The other day I asked my teacher if there was a book I could buy that would explain things very simple and easy, her answer was yes and she gave me the title, so all excited I went to the book shop to look for the book, I found the book and as I opened the book it slapped me so hard I dropped the book, I could have sworn it was it was a law/legal book I could not understand a bloody word in it.
Simple ? Basic? Stupid teacher is on drugs maybe that is why we are learning nothing.
The teacher is a sandwich short of a picnic and thinks the whole class is stupid as her, for example, the bitch makes us have name tags! How hard is it to remember 10 names ? Most being English as simple, Tracey, Keevin, Naomi, Alex, Sylvia, heck I am braindead and I remember everyone's names! Even our handwriting she bitches about, "oh how am I meant to read this mess"she said.. Well with your eyes bitch and if you don't understand it then your teaching us the wrong language, oh and we have to use a blue pen and paper with lines, now graphic paper, oh please get a grip before one of us "aliens"slap you for a six.
Oh and I did find are really good book that is helping me a lot with my grammar, no thanks to the teacher who thinks she is queen shit!
