Which sister--Olivia or Nancy--is the one who is able to get things accomplished?

This lunch meeting was called essentially so that Nancy could feel that she was doing something--without actually having to do something. It will be clear that Nancy is a woman of words alone who feels the world owes her everything and does nothing of value. Olivia, on the other hand, is a woman of action and knows her strength. She respects her mother and realizes that her mother is an independent and capable person.
