That's how I titled my response to a thread (on a non-religious discussion board I frequent) asking: "In honor of the Lord's Baptism today, were you baptised? (Poll)"
I was baptised at 18 as a Jehovah's Witness. When you've been raised as a Jehovah's Witness, at 18, you have all the worldly wisdom of an 8 year old.
It's a bit like signing a death warrant, as every decision you make from that point forward is done with the realization that there is a cocked, safety off, gun pointed at your head.
Of course, by the time you get to that point, as a JW kid, you've pretty much lived your life with a gun pointed in your general direction, poking you towards the baptismal pool.
