I like to take the more direct approach, You could tell her as the head of the house
(her head ship) In the best Interest of your family she should not go to the hall or studies.
Or ask her questions she cant questions she cant answer. Example: If the society is Gods
only channel for spreading the good news why have they been spreading the false news for the past \
100+ years.Your hope here is to get her to think for herself and not have the society think for her.
good luck---> oops I mean best wishes.....
