There was a knock at our door this morning. "Hi", said one of two callers - a man and a woman - who stood on the doorstep, "we're Jehovah Witnesses."
"Come on in", I greeted the pair ... my expression [doubtless] more of a grimacethan a welcoming smile.
"So, what's your latest line of patter then?"
"... d'damned if I know", the first visitor stammered, shaking his head while registering the look of shock
on his companion's face,
... "this hasn't ever happened to us before!"
