Are You A Curmudgeon?

Was reading an article in the Paper recently, where it called a former Prime Minister of Australia, an “old curmudgeon”. Now according to an on-line dictionary, a curmudgeon is an ill or bad-tempered, difficult, cantankerous person, full of resentment and stubborn notions.
Now, any one with a little more than a base Knowledge of the former Prime Minister, would say that that description pretty well sums up Paul Keating to a tee. But what of you? Does it also sum up you, or even me, too? Yes are we too, more often than not, bad-tempered, difficult, cantankerous and full of resentment and stubborn notions as seen by others, even if we ourselves tend to think we are the only intelligent people around?
I guess what I am asking today is, do you really see yourself as others really see you? Or are you a curmudgeon without even knowing it? Over to you for now.
