A long time ago my wife was bratting me and demanded to know why I got to make up the rules. (À la ‘who said that was the rule?’ and ‘Well, I don’t see it written down!’)
There’s a post-it with a hastily scrawled “I am the law.” on it that I use up as ‘proof’ of my claims to domestic power.

Mind you, that’s all for play. We don’t fuck with anything that could violate consent.
