@Germlat,
That sounds ridiculous to me Germie.
He might have been better saying Intelligence is the wife, a fanciful proposition, imagination is the mistress, in the initial phase at least, and the casual encounter is the servant.
Not that I would say anything so superficial and dishonest in the first place but if I was to do, on an arty-farty TV discussion aimed at self-improvers, say, I would say something like that and recross my legs for a full stop and ponder whether my wife, my mistress or my servant hadn't changed her mind about the tie she had insisted I would look good wearing.
