Did Mrs. Hale change as a character?

In
"Trifles," Mrs. Hale doesn't change as a character, but she gains a heightened
awareness of how she has failed her old friend Minnie Wright.

From the start,
Mrs. Hale is more sensitive to the "trifles" that the men dismiss and overlook. She
knows, for example, if the men do not, that the mess in the kitchen is not due to Minnie being a
poor housewife: she realizes from the start that it is a sign Minnie was under duress.

It becomes more and more evident from the small details that Mrs. Hale and Mrs. Peters
find that Minnie must have snapped and murdered her husband after he wrung the neck of her
beloved bird. As the facts of Minnie's isolation and desperation become clear, Mrs. Hale
remembers what a vibrant woman Minnie once was. As she grows more aware of Minnie's suffering,
she begins to realize she should have reached out more to her old friend. As she says:

Oh, I wish I'd come over here once in a while! That was a crime!
That was a crime!
