Selma Richards is the boy's natural mother. At his birth, she was illiterate, unemployed, and a crack addict. Giving up her son was the best thing for both of them - at the time.
Selma is now off drugs, learning to read, and has a responsible job. She's not rich and doesn't live in the best neighborhood, but she's healed herself. And now she wants her son back.
Seth Margolis raises a complex and emotional moral question while giving the listener an understanding of the pain and conflict that leads to the inevitable heart-rending conclusion, in which one mother ends up losing her son.
