I frequently read on this Board that somebody has 'been a JW for over 25 years' and then learn that they are in fact 25 years and three days old.
So what's wrong with that? Some of us were living the JW life since we were in nappies. We had no other choice. No birthdays, no Christmases, having to tell friends that we can't go to their party because "it's against my religion". Going door-to-door in prams. stollers, toddling along with our parents, even though we didn't understand fully why we were doing it.
So in that sense I've been a JW for 30-something years
But I won't say when I was baptised because that would make it easier for the elders to ID me, wouldn't it?
