If someone says "close the door" and I slam it shut, did I do as s/he asked? And if a third party is asked to decide, to designate my action—name it—as closing or not, how does s/he do it?

Strange that a culture that views the Oxford English Dictionary as opposed to a government administration as authoritative for language should be the home of a theory of law as the reverse.
