I'm just not very good at dodging those questions gracefully. I don't know how to respond to those without making her angry.
You begin by rejecting your own premise, John:
Whether or not your response makes her angry has to become comletely irrelevant to your way-of-thinking. Or at least, SECONDARY to the far-overriding factor of "Is this The Right Thing to Do in this situation?" Until you LOSE THE FEAR that your responses will "make her angry," you will NEVER get anywhere.
