DO NOT GIVE THEM CONTROL! IF YOU GIVE IT TO THEM THE WILL TAKE IT!
We have had this happen to us. Use the not feeling well/work schedule excuse as much as you can. If they start digging further, tell them you have some personal issues but give them NO details.
The miranda rights state, "anything you say can and will be used against you." It goes for the JW police as well. As soon as you start talking they WILL hang you. Guarantee it. Also, if you give them NOTHING it will drive them insane. We all know JW's are the nosiest people on the planet and thrive on rummaging around in your underwear drawer and going through your movie collection.
The miranda rights also state that you have the right to remain silent. Do just that!
We are having a great time watching these fascinating people try to figure out what is going on with us. It's a mystery!
If they become too intrusive tell them to mind there own business and get off your back. I'll repeat...IF YOU GIVE THEM POWER OVER YOU, THEY WILL TAKE IT.
Relax and enjoy the ride.
