Symbolically, what's interesting about Hughes' description of Mrs. Jones' purse?

"Thank You M'am" is Langston Hughes's short story about an encounter between a black teenaged boy and a woman who takes him under her wing (both literally and figuratively) after he attempts to steal her purse. Hughes describes both Mrs. Jones and her purse in the very first sentence: "She was a large woman with a large purse that had everything in it but hammer and nails."

"Thank You M'am" is Langston Hughes's short story about an encounter between a black teenaged boy and a woman who takes him under her wing (both literally and figuratively) after he attempts to steal her purse. Hughes describes both Mrs. Jones and her purse in the very first sentence: "She was a large woman with a large purse that had everything in it but hammer and nails." Just from this description it is evident that the purse is symbolic of the power of Mrs. Jones. The purse contains a great number of things and suggests that Mrs. Jones is always prepared for whatever she may come across. Because of its weight and Mrs. Jones's strength, young Roger is unable to steal the "pocketbook," as Mrs. Jones refers to it. It is obviously larger than a pocket. The suggestion that it could hold hammer and nails also reveals that Mrs. Jones is, metaphorically, a builder, and in this case she hopes to build Roger's character by showing him kindness and that the world is not as cruel as he may have thought. It is also a symbol of the respect which Roger displays toward Mrs. Jones. Instead of taking him to the police, Mrs. Jones cooks him dinner and even gives him money to buy the shoes he so badly wants. Later in the story the purse is representative of temptation and the immediate maturity that Roger shows when he resists taking it, even though it has been placed in clear sight:

The woman did not watch the boy to see if he was going to run now, nor did she watch her purse which she left behind her on the daybed. But the boy took care to sit on the far side of the room where he thought she could see him out of the corner of her eye, if she wanted to. He did not trust the woman not to trust him. And he did not want to be mistrusted now.
