That is a very typical repsonse from a micromanager. As I said before, they don't tend to like people to know that they don't have their priorities in order, so they give general response like this. "Just do them all.." They also typically avoid answering emails as well, because this tends to require a response that that they can be quoted on later in a meeting. Micromanagers typically change their minds all the time, primarily because they don't have a clear battle plan or methodology. So as a result, they do not like anything that can possibly pin them down.. Like I said, they can be the most frustrating and demoralizing force in the workplace. I tell folks all the time that don't answer emails, "You are in the IT business and that requires communication, if you don't like answering emails then maybe you should consider another line of work." :-D
