I used to say I'm always right because when I'm not I say it (or I admit I'm not sure). It came out as being arrogant so I stopped using it publicly. But it's true. When I'm not perfectly sure, I never act like so. I'm only comfortable arguing back when I'm totally sure, i.e. can point to the right explanation in a book or something similar. Friends find it a bit annoying.. because whenever they ask a question, I'm rarely comfortable answering yes or no.. it's always, well, it depends ;)
