Mr. Taylor says he saw a baby angel the night before, and heard the voice of his dead wife. His wife's voice said to him "I want some children," and Mr. Taylor tells the story in a frightful way. The story disturbs Maya. Mama thinks Mr. Taylor is mentally unstable. She tries to calm him down by interpreting "I want some children" to "I want you to work with children from the church."
