Design that age way too young! I was 17. No reason to ask Catholics why they were baptized because it strickly dealing with Jehovahs Witnesses. But I see what you mean because JW like to answer question with question regarding "Christendom" doctrines. They love to compare instead of answering the question. Good at pointing out other religion doctrines instead of their own.
Punkonice they can count time for any reason, let them start counting. But they do get annoyed when I tell them they can not count time with me because I am baptized. A few already tried that one.
As far as time, I find it strange how Jehovah's Witnesses neglect to realize the time after Jesus changed Christians dedication to follow Jesus and proudly boast him as the Messiah.
Baptism for Christian should symbolize following Jesus Christ and beliving he was the Messiah the son of God. Yet with the JWs it is backwards.
