Reactions to my "twinge questions" are met with either thanks or annoyance. That's OK, because I know the value of my own twinge meter.

On the other hand, when someone else is asking questions, I can usually tell the difference between micromanagement, ignorance, and true twinge. I try to listen and think before reacting, because anyone can have a twinge.

Experience isn't everything, but it sure can save a project.
