Due, Mormons USED to come to my house.
They don't any longer - 'cuz I would talk with 'em - and use their own scriptures to teach them.
Ditto with Jehovah's witnesses. With JW's - they always have an older 'more experienced' proselytizer paired up with a green weenie. I always talk with the older one - and, usually, after about five minutes - they are in a really big hurry to scoot that impressionable neophyte outta there. *lol*
As I said ... USED to come by here. Still chuckling.
