Women have been brought up to be passive, accepting, not come forward and play a major role in life. And with age, there's a tendency to revert to that - to pull back, recede. I don't think it's advisable or admirable.
I went to Catholic school. Do as you're told; don't ask questions and you will be illuminated.
The choice of roles as I grow older gets more and more limited, so if I pin myself to one kind of part I would get in trouble. So, these oddball ladies came along for me to do - I guess Terry Gilliam helped in this respect. I have found them more interesting, flashier and I get more mileage out of them.
