What is a short summary of the story, Loyalty, in the collection, There’s Something I Want You to Do: Stories?

Loyalty takes place in Minneapolis. Wes is a car mechanic. He used to be married to a woman named Corrine. They had a son—Jeremy—but Corinne soon became overwhelmed at the prospect of being a mother, so she left town, and she and Wes divorced. Wes soon remarried. About 16 years later, Corinne returns to Minneapolis. She is destitute and is suffering from mental illness. She asks Wes if she can stay in his home for the time being. Wes feels a moral obligation to accept this request. Astrid and Jeremy are not happy with this turn of events, but they recognize the moral necessity of helping Corinne.
