At the beginning of the story "Thank You Ma'am," Roger is portrayed as a young boy who attempts to steal Mrs. Jones' purse. The text evidence that supports this is when he tries to snatch her purse but fails. However, as the story progresses, Roger undergoes a transformation. At the end of the story, he shows remorse and gratitude towards Mrs. Jones. This is evident when he says, "Thank you, ma'am, for not turning me over to the police." This change in behavior demonstrates Roger's growth and development throughout the story.
