had the same happen only I was dressed to go to town, courthouse i think. The guy wouldnt leave I did get rude and pointed to his bible and said "you do know that book was written by human beings don't you...?"
I just tell em I am a registered sex offender or convicted felon while I stare at the youngest male or female in the bunch, and they take their Watchtower with em when they blast off to the next neighborhood in short order.
