How do you view Surprise?

When you hear the word 'Surprise', what comes to mind? Is it a pleasant feeling or that of shock - as in bad shock? Well, I've heard people say with emphasis, 'I HATE surprises!' To these ones, they don't care if it's good or bad; they just prefer to be in the know before anything happens - but this does not always apply in reality (the world is filled with many surprises).
