Just because she acts like this on TV, in front of people for her job, does not mean she is like this all the time. She may be very quiet at home with her folks, in her own room, but likes the energy of other people in the house, then goes out to the main rooms and becomes talkative again, sometimes. I think the relationship she has with her parents is absolutely wonderful! Our society puts way too much emphasis on "independence", blah, blah, blah.....
I think its all crap; True "independence" comes from being able to be interdependent.
