An housbonde shal nat been inquisityf
Of Goddes pryvetee, nor of his wyf.
– Geoffrey Chaucer
The Canterbury Tales, The Miller’s Prologue. Men should not try to discover the secrets of God or the secrets of their wives, the Miller advises the Reeve. He says this after the Reeve objects to the Miller’s tale about a carpenter’s wife cheating on him and making him a fool – the Reeve is a carpenter.
