Actually the males were her adult nephew (on her dead husbands side) and a friend of his. He had been raised in the home from a very early age(apparently had been breastfed along with one of her own children). But as he was not a direct blood relative is not allowed to see his aunty or help her, particularly after he has left home.
The mingling was actually the delivery of food. She was unable to leave the house un escorted by non existent relatives and her good nephew was delivering food.
Apparently widows who's children do not live nearby or who have no children are expected to starve to death. Other women can not deliver food because they can't go out either and if they bring their husbands the anti mingle laws are still broken.
