The advantage of knowing everything
Before you can know whether someone is wrong, you have to shut up and listen to what they’re saying… unless you have all the answers. In that case, an idea coming from someone else must be wrong because if it were right you would have thought of it.
This rather enviable situation means you need listen to others only until you work out which of your ideas they are talking about. As soon as you match their rambling to one of your own thoughts you can stop listening. Often you can save everybody a lot of time by interrupting with a parade of your own succinct yet awesomely complete understanding of the subject.
Of course, if you can’t match their rambling to your own thoughts then clearly they are spouting rubbish. You are practically obliged to interrupt, whether or not they were talking to you.
Curiously, people are completely ungrateful about the gift of your correction. They don't seem to grasp that you are protecting them from making fools of themselves, and are apparently oblivious that their poorly considered twittering interrupts your thoughts.
