I was a right one as well.
Although if a teacher was sound, then i was too.
I would take a punishment for being 5mins late no worries, but i had a teacher (my form tutor teacher) who would put you on detention for coming in the class when the bell was still ringing (no s***). A 30min detention after school, this was in my 1st year of high school, so i took it, about 4-5 times as well, then something snapped, I told him to fuk off, told him if he booked me again i'd rip his face off, proceeded to throw a Bunsen burner at him, and filed an official complaint in with the headmaster just after i stormed out the class punching the walls.
He was a bully unfortunately, and his victim was me, its where my temper evolved from, its also why now i can never let someone get the better of me, was such a nice boy.

Fuking dick, hope he's dead tbh.
Ps: Rant over
PPS: Teachers are c***s just as much as pupils.
