I turned down the offer to be an Elder a couple of times, not that I did not want the responsibility entirely, I certainly never wanted to be responsible for DFing anyone, but I hated the Politics, the obvious deference shown to Elders, which I saw as undeserved, and it generally being a Club I did not want to be a member of.
I also knew that I would take the pastoral work that Elders SHOULD do seriously, and having an exacting and tiring Job, plus kids to raise, I felt that I would get burn-out in no time.
I am glad I never became one, there is less guilt for me to carry, I have enough for simply being a JW for way too long.
