Forewarned is forearmed! Here's a little tip for anyone who decides to 'phone Bethel:
Bethelites are trained to be paranoid with telephone callers, and they ask you the following, "Who's calling; where are you calling from; (if you've withheld your number!) are you one of Jehovah's Witnesses?; what congregation are you in?"
If you give your name, they will normally refuse to give you theirs afterwards, so here's how to put them in a corner - when they ask you for your name, don't give it yet, just ask, "To whom am I speaking, please?"
They realize they cannot refuse to tell you, otherwise you will do the same!
When they ask the other questions, simply say that you 'phoned up to ask a question, not to give out personal information.
