Answer: Mrs. Jones said this to Roger, a street boy whom she brought home.
*The incident of Roger reminded Mrs Jones how she had passed her days in her youth. She told that she, likely any other girl, also wanted things that she could not get. She said she too had to do something unfair in her life. She looked thoughtfully, and she wanted Roger not to go in the wrong. Perhaps she thought to help the boy so that he would not make mistakes anymore. That's why, Mrs. Jones commented so.
*Roger reacted strangely. His mouth opened and he frowned unwittingly.
