That’s a false dichotomy. It is not the difference between the teacher doing everything and the teacher doing literally nothing (“if nothing is laid out for me”). The expectation is that, in *your * education, the teacher should do their job to teach and you do your due diligence as a student to learn.

The latter point is what the post is about. Students who put in no effort at all. If that doesn’t apply to you, then you shouldn’t feel annoyed.
