Dave-
That's the thing I noticed, whenever I talked to someone at the door that was really into it they always knew the bible better than I did. I generally felt pretty stupid trying to talk to them about it when it was clear they knew it better than me. Of course at the time I had convinced myself that I still knew "the Truth" while they were blinded by Satan blah blah blah you know how it goes when we justify something to ourselves.
Now that I'm out I can see that they actually did read the bible, I just read the Watchtower.
