Lazy people everywhere. Lazy students who can't be bothered to do something as simple as an assignment and then complain about it. Lazy professors who repeat the same lectures for over a decade, don't give any feedback and don't give a fuck about what the pupils are learning. In my university we don't even get to see the corrected exam we handed in. We receive a numerical grade by email and that's it. I have no idea what that meant. It's disgusting... :(
