When tempted to vent your frustration in the form of a question ("What makes them think this is a good thing?" "Why are they asking us to do it that way?" and the ever popular "Who's bright idea was that?"), try imagining you are being asked the question and that you have to provide a serious, reasonable answer.
It might help. It might even put the situation into perspective. It will definitely provide you an opportunity to look just a little bit better -- better than you will if you blurt out the pointless question.
