Why is it that...

...when a teacher walks into the classroom ten minutes late, no one shouts at them.
...when a teacher forgets to bring a book or pen etc to a lesson, they don't get a black mark against their name.

...when a teacher forgets to mark the class' books, they don't get a homework concern sticker.

This, in my opinion, is definitely not fair.

Whatever happened to 'everyone is equal', hmmm?
