Night Women--Sorry I couldn't find the questions!!

Night women is about a woman who is a single mother to an adolescent boy.  She has no other means of feeding him and providing shelter for him except for taking part in prostitution.  She lives in a single room apartment, and often has to carry her business in the same room as her son, and even in the same bed.  She bought her son a pair of headphones so that he can try to tune of his mothers' sins that are taking place only a few feet away from him.  His mother does not do this out of pleasure, she admits that she dreads it; it is the only way that she can provide for herself and her desperate son.  She has thought of a fabrication that she will follow, for when her son wakes up while she is in the act of serving a client.  She tells him that the angels have sent back his father for the night.  I have a problem with this because not only is it lying, it is creating a fantasy world to the son, making him believe that angels can really bring people back to life in person.  Also, I think that if the child were to be told it is his father, he would want to speak to him, and get to know the man that created him.  In the last two paragraphs, the son says to his mother, "Mommy, have I missed the angels again?"  The mother replies to him, "Darling, the angels have themselves a lifetime to come to us."  This led me to believe that his father was never actually the mother's husband, yet simply another client.  I think that this quote is the mother telling the son, inadvertently, that his father was simply another one of her clients.  On the other hand, I do not think that his mother would be a night woman if she did not have to fend for a child, unless she was not financially adequate to provide for herself.  I think that this story has a lot of possible explanations, and theories that could be interpreted completely differently in different contexts.  My thoughts are that the father was someone she saw regularly, but did not marry.  I think that he did not die, he walked out once realizing that she was pregnant.  This could also be proved on the first page of the story, when she says, "[about the father] an old lover, who disappeared with the night's shadow a long time ago."
