Whoso that first to mille comth, first grynt;
I pleyned first, so was oure werre ystynt.

– Geoffrey Chaucer

The Canterbury Tales, The Wife of Bath’s Prologue. It’s a case of the lady doth protest too whenever the Wife of Bath criticized her first three husbands for being unfaithful. She only did it to get her accusation in first, in order to prevent them accusing her of the same thing. Is that because she was an adulterer? Remember earlier in the Prologue she warned wise wives to never let husbands catch them in an affair!
