What is the cause of Mrs. Jones's stress?

The cause of Mrs. Jones's stress is Roger, a boy who tries to steal her purse while she is on the street. Mrs. Jones, however, takes hold of Roger before he has a chance to steal from her and questions him about why he would do such a thing.
Instead of reporting him to the police, Mrs. Jones transforms her stress into compassion. She takes Roger to her home, gets him washed, and gives him some supper. She also asks him why he wanted to steal her purse, prompting Roger to confess that he wants a pair of blue suede shoes.
Mrs. Jones understands what it is like to want something when you don't have the money for it. As she comments, she was once young and wanted things that she could not get.
In the end, she gives Roger the money he wants and sends him on his way, proving that her compassion is far stronger than her stress.
