Describe what type of person Minnie Wright was before her marriage.
Clearly, if you read the story carefully, you will see that through the various reminisces that Mrs. Hale has of her friend, Minnie Foster, before she became Mrs. Wright, she was a social woman who sang in the choir. Note how Mrs. Hale refers to this memory that she has of her when talking to Mrs. Peters, who doesn't know Mrs. Wright:
"I wish you'd seen Minnie Foster," was the answer, "when she wore a white dress with blue ribbons, and stood up there in the choir and sang."
Of course, this memory of the young Minnie Foster, who used to wear "pretty clothes" and was "lively" is a far cry from Mrs. Wright, who seems to have had the life choked out of her by her harsh and stern husband, Mr. Wright. We can therefore see Minnie Wright's act of murder as a final explosion of all the pent up anger and frustration at having been kept down for so long and forced into isolation by her husband.
