What kind of person was Mozart portrayed? Please use two examples.

Mozart is portrayed as an a fun-loving eccentric genius. Mozart is a genius, but an infantile man. He spends beyond his means, parties too much, and defies authoritative figures, including his father, Leopold. These negative traits all contribute to Mozart's downfall, but what truly hurts Mozart is his arrogance. His arrogance turns Salieri, who could have been a powerful ally, into an enemy. Mozart finds any and every opportunity to insult and humiliate Salieri. As a result, Salieri begins to see Mozart as an instrument that God uses to mock him. Salieri wonders why God gives a vulgar man like Mozart exceptional skills, yet makes him, a pious man, mediocre.
