Baptised when I was 13. I wanted to wait but some sister said "Why wait?" Of course, at that time I was a true believer. Wasn't old enough to buy cigarettes or even drive but somehow old enough to make a lifetime commitment to an organization.
Looking back on it I wish I hadn't been homeschooled through high school and that I never got baptised. If I was in high school and not baptised, I probably would have never gotten baptised.
