Here’s Tyrion Lannister after telling the story of his marriage’s demise to Bronn the sellsword:
After a time he heard the noise again, the rasp of steel on stone as Bronn sharpened his sword .
“Thirteen, thirty or three, I would have killed the man who did that to me.”
Tyrion swung around to face him. “You may get that chance one day. Remember what I told you. A Lannister always pays his debts.” He yawned . “I think I will try and sleep. Wake me if we’re about to die.”
