Calpurnia is portayed as an outsider in chapter 12 of To Kill a Mockingbird. Her claim that she ‘doesn’t have a birthday’ shows that she isn’t particularly valued as an individual. The contempt towards her from both the white society, because she’s black, and members of the black community, such as Lula, because she works for Atticus and his children. She wasn’t even acknowledged by her own son. To me, this implies that she is in between two communities and is valued by neither. This generates sympathy for the character.
