Hopefully, your college student has a good working relationship with their class professors. The relationship between a college student and their professors, in addition to the formal teaching done in the classroom, is often an important mentoring opportunity. Of course, having a good relationship doesn’t necessarily mean that each professor will be on your student’s list of favorite people, but hopefully, they have at least found how to make each course work.
But what does your student do if things go wrong with their professor? What if they have a serious problem that seems to be getting in the way of success in a course? What do they do then? Perhaps they pick up the phone and call home. This would be a good time to provide that important listening ear, and perhaps some sympathy, but it is definitely not the time for you to pick up the phone and call anyone at school. This is an important time to help your student think through the situation, consider alternatives, and create a plan of action.
