We've all had our share of terrible teachers and stories from public school.
It's a pretty popular rant subject.
And it's also now mine, even though everything is my rant subject because complaining is my hobby! Here's a few!

So my class is pretty dirty minded. And either my teacher was really creepy or very not dirty  minded. Whenever he explained something, he did it in the wrongest way possible, and all the kids would just look around at eachother awkwardly not knowing whether they should be trying not to laugh or trying not to cry. ESPECIALLY in French. But that bit, comes later. Here's a story from like idk technology engineering stuff:

So we were makin this little pop up Jack in a box type thing, and we had to push a straw into a silicone tube. And oh my god I wish you could have been there when he explained how.

He brought us all down to the carpet, and he said "now it's really hard to push the straw into the tube" and he starts pushing it in and says "And now you gotta push it in REAAAAAAAAAALY hard, just push that in there" and we're just sitting there like, does he know what he's saying?
"Just do it like that, push it RIGHT in" and he rolls his Rs like he's attempting a really Scottish accent.
"And you just push them in there like that!"
But wait- it gets dirtier. 
"NOW YOU JUST PUSH IT IN RRRREEEAAALLY HARD. I'VE DONE IT TWENTY TIMES."
And the whole class is already starting at eachother, horrified. And the day ended with us unable to unsee that he's "done it twenty times!"

I've got another rant up my sleeve about that same teacher, but let's move on to another teacher. Mr Errington. A substitute teacher. You already KNOW how bad he is, he's a substitute teacher...

He was called Mr Errington and man did he scare the hell out of me.
I mean he sometimes scared the living hell out of me
Sometimes he just didn't make sense
One time he just shouted "D'YOU KNOW WHAT CHEESES ME OFF"

...Like who in the world says that

Also, you know how when you're doing painting in art everyone starts talking, just y'know, making jokes about how they just got paint everywhere, asking to borrow white paint from the person next to you, laughing that kinda thing?

Yeah mr Errington's not a fan of that...

Whenever he heard people talking, he would whisper  really quietly " ...can you please be quiet" and no one would hear, THEN, he would slam a student's table as loudly as possible and stare at us all like we just murdered his mother.

Also he called us idiots a lot.

Little end note, I might make a part 2 if you want. Btw I couldn't be bothered editing this one so please forgive me if there's any weird grammar or bad spelling.
