One of my Province confreres today expressed how lucky I am, being a Brother, at not being able to hear the confessions of Sisters. While sharing his experiences in the confessional he stated that very many of the Sisters experience real hell here on earth in their convents... and yet he said, 'I don't understand why they opt for this "imprisonment by agreement"!
I guess that is an option we all make for our own reasons. Furthermore, why we stay on too has numerous reasons. It all depends on how each one perceives it and is willing to live it to the best.
