They are scared.
Very very scared.
Everytime they see you or think of you, they are reminded of their own private doubts.
I had wondered about that. I know I have really forced at least one elder to think. I asked him if he thinks of me every time he reads the name Jehovah in the CGS in NWT, and to my suprise he admitted---"yes." (eight elders and two former so far I have spoken with about this and not a single one ever knew or noticed true use of name Jehovah in CGS in NWT).
