Bertha
Even though we never actually meet this big, pesky Bertha, we feel like we know her—and we don't like her. Townsfolk of all sorts constantly insult her and seem to view her with absolute disgust. To make matters worse, she calls for Sykes outside of Delia's house. She even goes inside their house when Delia's not there.
He done had dat 'oman heah in mah house, too. (88)
While Bertha's not the sole source of Delia's unhappiness, she's a pretty…big part.
