Pretty funny list, but this seems like a case of poor management of expectations. It shouldn't be your job to explain why things matter (as in 'Boss: What difference does that make?'), but sometimes that's reality.

Here's a set of slides on taking control of poor communication situations and learning to efficiently keep managers in the feedback loop. Sometimes it doesn't work out ('Boss: I haven't had time to get caught up on my email.'), though it's certainly a start.
