How annoying it is to be annoyed! If I make a mistake, I could laugh it off and say "I am an idiot". But if someone else, particularly those already lacking in social grace, were to laugh louder and continue to banter the same proclamation: "HA HA HA, YOU ARE INDEED AN IDIOT!", it diminishes the humour from the situation and does not sit kindly. This most profusely annoys me!
