Yeah, she's writing letters like they tell her to do in the KM. The KM tells the JWs to show the same respect to telephone witnessing and letter writing as for door-to-door. They TELL them to dress up just the same. She is being obedient. It is sad, but she is NOT a psycho. She is brainwashed.
Now how do you think she will feel if she finds out that her brother is calling her a psycho publicly and to strangers. Do you have any siblings? and do you treat them this way for something that is not hurting anyone except them?
You know, I wonder how many people here are estranged from witness family because they acted like jerks when they found out the truth about the truth and called family members psychos and other asshole things like that?
