So true, Maximus. And I do repeat myself quite often with the students. I suppose that is true of a lot of jobs, though. Hell, we often just repeat ourselves over and over on this forum.
I also dislike the student's argument that he's paying good money for his education and should get service. I lament the slide of education into a service based industry. They forget the service we provide is education, critical thinking, and really, growing up into an adult. That's what they are paying for. And it is certainly not the only way to get those things, so if they don't like it, they should do something else. And I tell a lot of them that, too.
