They should have cut her off at 18, of course
Apparently she had full ride offers her parents passed on. They WANTED the control of paying her tuition . “Comply or we cut you off”
That is total crap. Otherwise, in any normal situation, I have no issue with a parent cutting off a kid at 18. But then they also relinquish the right to bitch about happens later.
I have a hard time picturing any ‘normal’ historical parent prior to doctor Spock thinking they have the right to control the life of an adult child.
