There is a new show on NBC this season called Madam Secretary starring the talented actress Teo Leoni. My favorite line in the season opener was when the Secretary of State (e.g. Madam Secretary) was told about her boss's order (e.g. The U.S. President), "You don't have a choice." And her response, "Here's the problem. I've never met a situation where I don't have a choice in the matter."
I like that attitude: With respect, do not defer.
