In what way does Melchor subtly suggest the true purpose that the Witch had served within her community prior to her death?

In Chapter II, the narrator lists a few maladies and problems for which women in the community would seek out the Witch's help before her death. The reader learns that the women in town would seek out the Witch's help for all manner of troubles, including help for a husband's constipation, "a tea to keep tiredness at bay, or an ointment for tummy troubles" (10). After providing this list of seemingly mundane requests for assistance, the narrator hints that the true value of the Witch's presence in the community was her ability to listen. Melchor writes, "Let's be honest," going on to say that one boon of a visit to the Witch was "just to sit there a while and lighten the load, let it all out, the pain and sadness that fluttered hopelessly in their throats" (10).
