Teachers have it so difficult. They're responsible for YOUR academic future, they're responsible for the future generation to be properly educated and in their spare time, they're marking books, planning lessons or even doing revision lessons without extra pay.
I can understand teachers can be bullies or racist or sexist or homophobic whatever but that's the only excuse because I've called a teacher a bitch because she was getting on my nerves but I did apologise the same day because it was disrespectful of me.
However, ruining your teachers life just because of a class or whatever?

Karma is a bitch anyways, and you won't see karma coming.
