No child borne to a Witness was raised in the "Truth". They were raised in a "Cult".
Besides, the age at which your parents began studying and were baptized, has nothing to do with your baptism.
I was borne into the cult, baptized at 17. I finally got out about 10 years ago and none of my Witness family speaks to me; not even my 21 year old daughter.
And that Elder sounds creapy.
