As regards to Holly's goodbye;
Another possible explanation exists which was touched upon. If Holly is deaf, and isolated, then being cut off from the person she was studying with would be a double whammy. It is almost as if she was disfellowshipped, and if she is alone, and not a strong willed person she may have felt that the personal attention she got from the JW?s was worth lying to herself and others to gain.
Her parting shot may have been her way of proving to them, and if they know she was here they may well have been watching her posts, that she was through with us and ready to be a good little zombie.
It would be interesting to compare her IP address to any newcomers in the upcoming months to see if she does pop up and post under a different name. She had way too many questions to just turtle like that unless there was another explanation, that is unless she is completely stupid which I doubt. In that case though, all is lost...
Leaves me going ; hmmmmm.
