There are questions, and there are questions. You learn which to react to, it's an experience thing. You also learn about people who want you to do something, only to have you redo it, and redo it yet again, until it's back to the original state. In which case, you learn to do nothing. And there are people who think they are important, but in fact it's _your_ job that's more important. Postpone it, maybe they pester someone else or it can wait.
