meek, demure daughter
I've seen this film several times and more and more I notice that Frank and Cathy's daughter is always interrupted when she tries to add to the conversation, or dismissed when she tries to display a ballet movement or whatever she's proud of. Yet she doesn't react in a negative way when her entire family completely ignores her, she simply remains quiet and says no more.
Let's say she was about 10 (or so) when this film takes place, now she's a woman in her early 60's. What sort of woman are you now? Did you find a voice?
