Who is Clara from I'm Not Rappaport and what is their importance?

Clara is Nat's daughter. She worries about her father's mental condition, as well as his health, and from the moment she arrives, Clara makes it clear that she would rather have her father living with her or in a geriatric home. Nat tries to prevent this by creating stories that get him off the hook, but ultimately, all of his stories backfire. Eventually, Nat agrees to the move.
