In college you’re all adults who are there by choice to learn. But also many students are fresh out of highschool so it’s a fine line colleges have to walk between respecting ones rights and keeping the student body in order (and not letting the bad decisions of individuals become the reputation of the institution)

Adults can make a decision about if a phone call is important or not, if they need to dip out early or not, etc.

But yeah it’s kinda wild the hard shift in responsibility from being a minor to being an adult and ideally there’d be better transition for kids as they cross that bridge
