What is the theme in Leaving the Yellow House by Saul Bellow?

The theme of identity is important in "Leaving the Yellow House" as Hattie strives toward some sort of self-understanding. Hattie has lived for decades under a cloud of self-deception. For instance, she pretends that her drinking is not as problematic as it is, and she pretends to care for India when she really feels that the other woman treats her like a servant. She blames her neighbor Pace for the disappearance of her dog when she killed the dog herself. After breaking her arm, Hattie realizes the extent of her reliance on other people, but she also realizes there are very few people, if any, whose assistance and love she can count on. This epiphany contributes to her attempts at self-exploration.
