Dorothy: Ma, when are you gonna get the results of the blood test? I'm a nervous wreck.
Sophia: It'll only take a few minutes. Relax, would ya?
Dorothy: Oh, Ma, how can I relax? Any minute now somebody can walk in here and tell me you're not really my mother.
Sophia: Let me remind you of something that may set your mind at ease.
Dorothy: Are you going to tell a story?
Sophia: No, I'm gonna sing a Negro spiritual. Shut up and listen.
