I live on a Jehovah witness training run so they call about once a month. I tell them I'm a Deist and they normally leave quickly.
However on one occassion the senior JW said she always wnated to meet a Deist so I invited them in for tea. Of course as a Deist I do not proselytise, I let those who follow an organised religion carry on with their beliefs.
How do other folks cope when JW comes a knocking on your door?
