Because she thinks that her father is a giant man...

Introduction:
Kezia, the protagonist of the short story "The Doll's House" by Katherine Mansfield, is afraid of her father due to his strict and domineering nature. Her fear is rooted in the way he controls and manipulates the family dynamics, his disapproval of her actions, and his lack of empathy towards her feelings.

Controlling and Manipulative Nature:
Kezia's father holds a position of authority within the family. He makes all the decisions, including the rules and boundaries that the children must adhere to. His control is evident when he forbids Kezia and her sisters from visiting the Kelvey sisters, who come from a lower social class. This restriction demonstrates his desire to maintain social hierarchies and control who his daughters associate with. Kezia fears his authoritarianism and the consequences she might face if she disobeys his commands.

Disapproval of Actions:
Kezia's father disapproves of her actions that challenge societal norms and expectations. For instance, when Kezia brings the Kelvey sisters into the house to see the doll's house, her father scolds her and insists that she should not have associated with them. His disapproval makes Kezia anxious and afraid of his reaction, as she seeks his approval and fears disappointing him.

Lack of Empathy:
Kezia's father lacks empathy towards her feelings and fails to understand her perspective. When Kezia expresses her excitement and enthusiasm about the doll's house, her father dismisses her emotions and tells her to "not be a baby." This lack of understanding and empathy creates fear within Kezia, as she feels unheard and invalidated by her own father.

Conclusion:
Kezia's fear of her father stems from his controlling and manipulative nature, his disapproval of her actions, and his lack of empathy towards her feelings. These factors contribute to a tense and fearful dynamic between Kezia and her father, shaping her perception of him as an intimidating figure in her life.
