I think some of it is generational also. In their generation, they had to learn to take what they were given. They didn't have the options that are available now. Not only that, but the gender roles for women of those times could also have influenced her behaviour. The rest is simply genetic traits.

I know that I have genetic traits I have received from my parents that i don't like lol. My father's impatience and my mother's self righteousness. I catch myself at times feeling irritated with others because of my own flaws and it is as annoying to me, to know I am that way, as it is to others who put up with me.

Oh the joys of life.
