@chai2,
As you probably know, I signed up to be a postulant.
I was very confused, the nuns telling me I had a vocation. (I think I triggered that by telling one I wanted to be a doctor, thus maybe flagging myself as a nursing nun in India). This was a few years - but not that many - before women got to be doctors.
I'm resentful now, re those nuns, but try to get over that, that is the way of much of life.
Some of the nuns were dumkopfs, and some, especially the ones in grammar school, and the ones in my one year of catholic college, were sharp. The inbetween years nuns are the ones I rail about (no enjoyment of sex in marriage, quote Sister Mary Anthony, mortal sin)
