I carried it around with me when I was younger, but towards the end of my association with the Jehovah's Witness cult, I didn't even have one.
As Teel said above, it's funny to remind ourselves what a cult can actually do.
We carried around a card that basically said;
"I am prepared to die for the good of this cult. I know that by me dying in this way, the Watchtower, Bible & Tract Society will have some great marketing material to play with. I know that my story could possibly make the next Blood Article Watchtower and be a real strength to those that are weak".
Yep, that's the decision we were making guy's.
Oh dear, we actually fell for it.
