When I was studying computer science at university (second year). There was a girl, I'm not sure if she was crying or angry after this, but I didn't expect that.

Just to put some context, this girl was still asking "what's the meaning of i++?" in second year. And during a re-sit exam, the teacher who was asked the previous question, was the one who monitored the students.

And the girl made a mistake (it was something usual though) . She asked the teacher something that she didn't understand. Which means that she wanted the teacher to help her with the exam, but I'm not even sure that she realised that. And the teacher said : "You still can't do that? I gave you this exact problem during lessons and also at the first exam! Well don't worry... I'll give you the same next year :) "

Not really nice for the girl, but hopefully I didn't hear it directly or I would have laugh a little too much x)
