Field service is such a waste of time. I can count on 2 hands how many people I've known who came into the "truth" since I was a kid and I'm pushing 40. All that time and money spent in an ineffective method... I asked my mom once if her next door neighbors knew their very life depended on listening to her and becoming a JW? She said, well you couldn't tell your neighbor that. I said, why not? If you truly believe they are going to die any day now then how could you NOT tell them or convince your next door neighbors. Her brain shut down and the conversation died.
I was in a hall with family and many long time friends. A divorce in the family led to the happiest people on earth picking sides and ostracizing us. I moved a few states away it was so bad. Best decision I ever made. It allowed me to get out.
Know this, "worldly" poeple are much kinder and politer than you realize right now. My workmates always respected me and my beliefs. Wait until you realize how crazy all your long held beliefs are. You will realize just how kind and polite they have been. Your non-JW friends will keep your secret and actually help you. They will keep your secret and be very careful not to talk to your family about you. Trust me, they may politely respect you and your families right to be a JW, but they know how weird it is. They will be thrilled to help you in your exit. You will in fact get even closer once you open up and tell them what you are going through.
All the best wishes to you and your family.
