To actually bring a parent into the interview is just unbelieveable to me. Bringing a parent along to see a law school or a medical school seems fine, but it's a given that the parent is going to disappear when anything official begins to transpire.
I will say that I still involve my parents in pretty much every major decision I make, but it's come to the point where they consult with me over major decision they make, too. I like it this way. Even though we live separately, the family still functions as a unit on more important issues. I guess that will change when I'm married and have kids, but as for now, I'm happy with things.
To bring a parent seems to miss the point of having a job in the first place - independence!
