In three words, it was: age of accountability.
Defined as the idea that 12 or 13 year old children are old enough to understand witness doctrine and thus old enough to take a stand for themselves when Armageddon comes Real Soon Now. Or else they (might) die.
I got baptized because I thought it was the right thing to do and because I wanted to do what I thought God wanted me to do, but I got baptized on my thirteenth birthday (well, what would've been it) mostly because I didn't want to die when Armageddon came. I seem to recall being guilt-tripped (er, inspired...) by the the hardhitting baptismal talk at the district convention the summer before I got dunked.
I also wanted to be baptized so I could auxiliary pioneer. People just didn't support unbaptized kids who were trying to get more hours. Stupid, stupid me.
I was the first one of my friends to get baptized, and was also the youngest person at our circuit assembly, and boy was I proud of myself for that. (I also think it was partly because of me that my brother, 3 1/2 years older than me, got baptized the same day I did, because otherwise it wouldn't have looked right.) In my mother's view, of course, I was much more mature at 13 than when I decided to leave at 17.
Gah. If ever there was a true believer kid, it was me. But I was still a kid.
