I get that a lot. Mostly with different skill interaction, though. In those cases, I'm assuming she passed on the request to proper skill, and doesn't give a fig if the external action provided by the skill did its part or not.
On the other side of the coin... it's always sort of annoyed me that she still says "OK" whenever I ask her to turn something on that's already on--open a garage door that's already open. I'd prefer her to call out my senior moment and say something to the effect of "That light's already on, dummy".
