I'll skip the "my parents" part, because I'm an old, but ... NO ONE had independent housing their Freshman year in college at my hometown uni, unless they had prior residency in the area (were commuting from home).
So, yeah: that morality did exist, and not just in fables.
I went to a mediocre undergrad, and a top 5 school for grad. The difference in morals was quite notable, and cheating was much more prevalent in the latter (not just in classes, but for things like this as well).
Sounds entirely consistent with the original story…everyone claims a mental health need because so many others are doing it.
Maybe the difference isn’t morality but accepted norms? Or maybe it’s that single room accommodation is possible now and it wasn’t then?
