Why does Olivia mourn?

Answer 1

Olivia mourns because she is deeply affected by the death of her brother, which has left her in a state of profound grief and isolation. She chooses to withdraw from the world and rejects romantic advances, including those from Duke Orsino, as a way to honor her brother's memory. Her mourning signifies not only her personal loss but also a broader commentary on the impact of grief on human relationships and emotional connections. Ultimately, her mourning sets the stage for the play's exploration of love, desire, and the complexities of moving on.
