I think if you're cornered and you have to talk to an elder or elders the old Watchtower theocratic war strategy might be in order. The elders are not entitled to your private business and so spinning whatever story with even a grain of truth is in order:
1. Use any family business that was discussed (oh aunt Peggy is ill) and blow it to proportions that warranted the 'mandatory' contact or...
2. Say that your 'apostate' cousin was having thoughts about returning to the organization but wanted to discuss it with a close family member first and NOT any elders.
3. You were having dinner on your cousin's request with the express purpose of discussing 'aunt Peggy' and/or his glorious return to the Watchtower. He didn't want to talk to any elders and would only confide in you but only in a social setting.
4. If after some time if you are prodded again just say 'aunt Peg' recovered and/or your cousin suffered a relapse.
5. If you are ever asked why you haven't been back to meetings you can say that you wanted to but after you we're photographed by the pioneer couple you now feel quite depressed and scarred. You're getting better and will return soon but you just need some time...
