Well, as a professor at a university, it's good you are acknowledging your child is now an adult...because I can't tell you how many freshman have parents that try to intervene on their behalf when things don't go "right" in a class. A federal act (FERPA) actually forbids us from even acknowledging a student is in our class to anyone, even their parents. Under FERPA, no matter the age, the student is an adult with privacy rights.
That said, the longer I teach, the younger the freshman look! Babies!
