A mother lets me watch her kids and says to me: Show the children a game. When she returns, she sees me teaching them to gamble with dice. She angrily exclaims I didn’t mean that sort of game! Must the exclusion of the game with dice have come before his mind when he gave me the order?
It’s true that she did mean not that sort of game. but she need not have had the conscious thought at the time of the request. Somehow her request made a normative division of proper responses.
If you find this puzzling that, nonetheless, what you did was an inappropriate response to her request, then you are trapped in a possibly Cartesian trap. You’re missing what distinguishes a sign from a piece of wood.
