Feste is a professional fool who belongs to Olivia, a rich Countess. He is very intelligent and witty. Even though he belongs to Olivia, he also entertains Orsino, Duke of Illyria. Everyone in the play clearly respects him and they generally do not treat him as a fool. They talk to him seriously, ask him for advice and join him in pranks. His realistic speeches are comical and light-hearted, but most of the time he makes logical points. He entertains the other characters in the play with his songs and jokes. Under the pretence of making jokes, Feste evaluates the behavior of those around him. It is quite interesting to observe how the other characters react to him. Olivia and Orsino both let Feste instruct them. Though Orsino has no appreciation for Feste's opinions, he values the fool's ability to sing melancholy songs.
