True story.... (from some years ago)
I was down my Mums house...where there was a bit of a family gathering. Nothing special, just a few of us all converging at the the same time. We were all just catching up with each other when my mum spotted, out of the window, JW's door knocking their way up the street.
When they got to my mums I was sent out to deal with the nusuience.
I answered the door and let them rabbit for a bit and then told them that I would be delighted to discuss our opinions on religion but at the moment I was busy sacrificing a cockeral to Beelzebub and if they cared to return I would be happy to discuss religious differences.
Never came back for some years after that. Funny thing is...they seem to have taken it seriously!!!
