People in the South are generally friendly. They are outgoing--gregarious. They enjoy socializing and planning or attending big weddings and barbeques, etc.
Emily is in conflict with the whole Southern outlook on life. She is withdrawn and lives in isolation. She will never marry because her father will not have it. By the time her father dies, she is no longer young and beautiful. She will remain a spinster.
This isolated life she lives is puzzling to her community. They cannot understand why she will not socialize. They try to visit but Miss Emily will not have visitors. She does not allow visitors because she does not feel like being social. She is quite unhappy, probably because her father was so strict and controlling.
