Well, from what I can see in your original post 5 years ago on the same subject, your college age student at the time had significant learning disabilities, so it’s understandable that you needed to be more involved. But that, along with some mistakes you made personally (failing a class because you forgot to drop it and had your admission to med school revoked as a result until your parents got involved and you were un-revoked) may have colored your views to a significant degree on the need for other parents to be equally involved.
I realize some kids do need more assistance along the way and why it’s necessary to hover in these cases, but there are many young adults who are perfectly capable of handling more responsibility on their own than they are allowed to. From my observations, the students more likely to mess up despite being perfectly capable were the ones who knew their parents were waiting in the wings to step in and fix their mistakes.
